[Bug 727486] New: frequent crashes in libdbus-1.so
https://bugzilla.novell.com/show_bug.cgi?id=727486 https://bugzilla.novell.com/show_bug.cgi?id=727486#c0 Summary: frequent crashes in libdbus-1.so Classification: openSUSE Product: openSUSE 12.1 Version: RC 1 Platform: x86-64 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Development AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: rcoe@wi.rr.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1 I use davmail to interface my mail client to an exchange server to fetch and send mail. I had no issues with davmail when running opensuse 11.4. I upgraded to opensuse 12.1 this weekend. davmail crashes frequently with a SIGSEGV in libdbus-1.so. davmail uses the swt package from eclipse, which is calling functions into dbus. I upgraded the swt package in davmail from swt-3.7 to swt-3.7.1, and it didn't not help. My next step is to build swt from source to see if that fixes the issue.

() When davmail works without crashing, I get messages of the form: (SWT:#####): GConf-WARNING **: The connection to DBus was broken. Can't reinitialize it. GConf Error: No D-BUS daemon running Where #### seems to be a pid (or thread id). I've attempted to debug this with gdb, but the java jvm does not initialize. I get class not found for a class passed in on the java classpath command line. I attempted to use MALLOC_CHECK_= with values of "", 0, and 1. Reproducible: Always I'm running with the sun java jre. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

On the openSUSE 12.1 release, this memory location happens to be mapped into area used by libdbus. I was running davmail with java-1.6.0_26-sun under openSUSE 11.4 with no issues. I first discovered the issue with the same java version with openSUSE 12.1. I tried using java-1.6.0_29-sun and also using libdbus-1.4.1 from openSUSE 11.4. I tried using java-1.7.0_01-sun, as recommended by davmail devel, and it works. This is not a libdbus issue. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
