Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: i586 OS/Version: openSUSE 11.2 Status: NEW Severity: Major Priority: P5 - None Component: YaST2 AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: george@grwelch.com QAContact: jsrain@novell.com Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7 I am on a remote computer. I connect to the openSUSE machine with ssh, try to run yast2, and it crashes on startup. local_machine:~ $ ssh openSUSE_machine -l root Password: Last login: Tue Feb 2 20:09:29 2010 from local_machine.dom.tld Have a lot of fun... openSUSE_machine:~ # yast2 /sbin/yast2: line 454: 12999 Floating point exception$y2ccbin $Y2UI_ARGS "$@" openSUSE_machine:~ # I believe the failure is related to the X server on local_machine. In the example above, local_machine is a macbook running OSX 10.6.2 and XQuartz 2.3.4. If I connect to the openSUSE machine with ssh from my neighbor's linux box, then yast does not crash. However, I have no problem running any other X program using the macbook -- it is ONLY yast that crashes. So basically, something seems to be wrong with yast that is exposed by the XQuartz X-server. Thank you for your attention, and thank you for writing such amazingly cool software. Reproducible: Always Steps to Reproduce: See details above. Actual Results: yast crashes on startup. Expected Results: yast should not crash on startup. Presumably the details above are enough. If not, I will supply any thing needed, such as logs etc. This is reproducible. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

...

Attach YaST logs, please (/var/log/YaST2/).

Lucas, That directory is filled with lots of personal information about my system (ip addresses, user names, hardware config, etc), that is probably not relevent to this bug. Here is the information that is probably useful: If I back up the log directory, then expose this bug (as described in the bug report) then no file in this directory is touched in any way. That is, YaST crashes before touching the log. If that is not good enough, and you actually need the logs, could you at least pare down the request some so that you are not asking for personal information? For example, would some subset of those files be enough? Thanks! --George -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

At least in which part is crashed. You can also try to find it using "time" in logs. Anyway, if you were running some YaST module after this crash, you will not find it at the end of the logfile. Additionally, logs are rotated. So, you might have to check also y2log-1, y2log-2 ... If there is nothing in the log, you can also try to reproduce it with debugging turned on: 1.) mv /var/log/YaST2/y2logs /var/log/YaST2/y2logs.backup 2.) openSUSE_machine:~ # Y2DEBUG=1 yast2 Then attach the resulting y2log file.

Check the end of the /var/log/YaST/y2log file, there should be something about the crash. At least in which part is crashed. You can also try to find it using "time" in logs.

No, there is nothing there. As I said, YaST crashes *before* touching the logs in any way.

...

Anyway, if you were running some YaST module after this crash, you will not find it at the end of the logfile. Additionally, logs are rotated. So, you might have to check also y2log-1, y2log-2 ...

Yes, I did this. There is nothing there, because YaST crashes before touching the logs.

...

If there is nothing in the log, you can also try to reproduce it with debugging turned on: 1.) mv /var/log/YaST2/y2logs /var/log/YaST2/y2logs.backup 2.) openSUSE_machine:~ # Y2DEBUG=1 yast2

Then attach the resulting y2log file. It should not contain any confidential information.

I did exactly this, includng the Y2DEBUG as you suggest, and /var/log/YaST2 was still totally empty. Nothing to attach. --George -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

what about `strace yast2 2>/logfile` ?

The result is attached.

or using gdb http://en.opensuse.org/Bugs/YaST#How_can_I_start_YaST_in_debugger_.28gdb.29....

This is harder. I downloaded the three debug packages referenced on that page. Then I run openSUSE_machine:~ # gdb /usr/lib/YaST2/bin/y2base and get this: GNU gdb (GDB) SUSE (6.8.91.20090930-2.4) Copyright (C) 2009 Free Software Foundation, Inc.

At random, I did this: (gdb) run repositories qt And it spewed several pages of "Missing separate debuginfo". Finally, it did this: Program received signal SIGFPE, Arithmetic exception.
