https://bugzilla.novell.com/show_bug.cgi?id=273700 mmeeks@novell.com changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEEDINFO |NEW Info Provider|mmeeks@novell.com | ------- Comment #6 from mmeeks@novell.com 2007-05-14 03:22 MST ------- Interesting - perhaps this is PEBCAK : when I run: Y2DEBUG=1 /sbin/yast update all is well & it works; extraordinarily curious :-) I assumed the wrapper was doing something clever, but in fact apparently not: Y2DEBUG=1 /usr/lib/YaST2/bin/y2base /usr/share/YaST2/clients/update.ycp ncurses also works just fine :-) most odd; then: /usr/lib/YaST2/bin/y2base /usr/share/YaST2/clients/update.ycp ncurses similarly works as you would expect; but adding: /usr/lib/YaST2/bin/y2base -l /dev/stderr /usr/share/YaST2/clients/update.ycp ncurses makes it crash repeatably - could this be down to the output to stderr / the console causing grief for ncurses (?) if I re-direct the output with the shell to a file eg. there is no crash. Alternatively perhaps it's a timing sensitive problem. Anyhow - unless it's obviously stupid, can re-test on the next alpha with a debuginfo package & get a better stack trace. -- 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, or are watching someone who is.

Yes, that might well be the case. See this line in the original y2log: 2007-05-11 15:08:55 <1> t60p(20793) [ui-ncurses] NCurses.cc(init):260 isatty(stderr)no Apparently it's not update.ycp that's to blame here, but y2-ncurses. I'll take care of this. -- 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, or are watching someone who is.

An ncurses program with logs on stderr is just guaranteed to be a mess, so I dare say that the crash is a better result in the end ;-) -- 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.
