Description Rubén Fernández Asensio 2010-06-20 19:12:45 UTC 
Application that crashed: kwrite
Version of the application: 4.3.5 (KDE 4.3.5)
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.13-desktop-1mnb i686
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
Kwrite stopped responding while editing an HTML file, and crashed when I closed it. Maybe because I had the same file opened in Opera, Opera Dragonfly & Firefox?

 -- Backtrace:
Application: KWrite (kdeinit4), signal: Segmentation fault

Looks more like problem in the file dialog used to open the file.
Comment 2 Christoph Feck 2010-08-07 21:20:28 UTC 
This bug is believed to be caused by Phonon::PulseSupport starting an local event loop. This has been fixed in Phonon version 4.4.1. For a detailed discussion, see bug 228324.

If you can still reproduce the bug with Phonon version 4.4.1, or on older Phonon version that is not compiled with PulseAudio support, please reopen the bug.
