doesn't happen here, can you provide some strace logs and gdb backtraces ? Created attachment 46663 [details]
gdb trace - but not useful as I don't have debuginfo package installed
Unable to use strace. When I start with strace, it exits from strace and then
it goes to background. Please let me know, If I can provide any other info.
I have installed only default GNOME. When I open konsole and press tab two
times for autocompletion, with this scenarios I'm able to reproduce this bug.
either strace -f knotify or strace knotify --nofork please. Created attachment 46671 [details]
knotify strace output
Started strace knotify --nofork in Shell 1 of konsole and opened Shell 2. Then
pressed 2 tabs in Shell 2 of konsole, CPU goes to 100% and lot of ioctl, read
calls started printing in Shell 1 konsole. Attached is console log info of
strace knotify. Please let me know If you need any other info.
ok, after some debuginfo installing it's very clear what the problem is: kdemultimedia3 isn't installed with "default GNOME". As such knotify has no idea how to play sounds on errors - and as such it gives an error - and then it doesn't know how to play sounds - and as such .... Adrian will fix that done Adrian: Will this be available with Beta 3 ? yes you can install "kdemultimedia3" for now as workaround. Created attachment 46687 [details]
After installing kdemultimedia3 (only) package knotify crashed
Attached trace from kde crash handler application.
Started knotify as
strace knotify --nofork
Adrian: Strace info - only snip of the complete console message, If you require
additional info please let me know. I'm always able to reproduce this crash.

can you please make a gdb backtrace also ?

() *** Bug 106255 has been marked as a duplicate of this bug. *** I can confirm the crash of knotify on my machine, too. It looks like the non-static functions in dl object disappears during a forked dmix server is running. Fairly complex case with a plugin in a plugin... A fixed alsa package is on bari-tiwai-6. Possible to try it out? I am not able to reproduce this anymore, lets assume it got fixed by the fixes. With Beta 4, I'm not able to reproduce this bug. |
