Description Eduard Sukharev 2009-06-16 19:48:23 UTC

Version:            (using Devel)
Compiler:          gcc 
OS:                MS Windows
Installed from:    Compiled sources

How to reproduce:
1. Open SystemSettings or run 'kcmshell4 kcm_phonon'
2. Chose any device (i had 4 to chose from, all of them just combination of DirectSound and my AC97 sound card device)
3. Press the 'Test' button and chose the audo filter on prompt (if you've already set it not to prompt it's ok - the outcome is equal with or without using ffdshow filter)

What happens: the SystemSettings or kcmshell4 module crashes

This only happens on KDE on Windows. Tested on Windows XP SP3, both precompiled binary packages (MSVC, release mode) and self compiled from trunk (MinGW, DebWithRelInfo).

Will attach the backtrace from selfcompiled MinGW version.

Edouard, could you please test with the phonon vlc-backend? Please also state the version of Phonon you are using.

Comment 5 Myriam Schweingruber 2010-05-03 10:19:29 UTC

Closing for lack of feedback. Please only reopen this report if you can reproduce it with the latest VLC backend and Phonon version.
