Created attachment 59522 [details] crash dump. Full crash report. Version: 4.0 (using KDE 4.4.4) OS: Linux Immediately after I login to KDE I see a report that knotify crashed every time. Something about a "segmentation fault." Reproducible: Always Steps to Reproduce: Running Ubuntu Linux 10.04 on an Intel dual core E3400 2.8 Ghz CPU with 2 gigs memory and Intel G31 chipset. After startup choose KDE and sign in and login. I immediately see a box saying Knotify crashed, "segmentation fault." Actual Results: crash notification, KDE still runs fine. Expected Results: It should have run quietly in the background until a fault occurred. Computer config above in "steps to reproduce."
What versions of gstreamer, gstreamer-plugins-good, phonon-backend-gstreamer, and phonon do you have? It looks to me like this is a pulseaudio alsa plugin bug. Odd that you don't seem to be using the pulsesink. Perhaps you've configured Phonon to not use pulseaudio?
10.04 did not use PulseAudio IIRC.
...not Kubuntu anyway
Closing for lack of feedback. Please feel free to reopen if you can reproduce this with Phonon 4.6.0 or later and provide the requested feedback.
