Sentry Crash Report:

Description Severin Stampler 2009-02-11 23:28:05 UTC 
Version:            (using KDE 4.2.0)
OS:                Linux
Installed from:    SuSE RPMs

Do as follows:
1.) Open any KDE4 application
2.) Choose 'Open File' from the menu or tool button
3.) In the File open dialog: browse to any directory containing videos
4.) Hover mouse over a video and wait for preview to start
5.) Move mouse to the tool buttons and go back in folder hierarchy (Video stops)
6.) Hover mouse over stopped video player --> CRASH!

I think that explains the problem.
kind regards

As you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks :)

Comment 3 Dario Andres 2009-02-18 21:41:39 UTC 
Does this happen with every Video file? (what extension/format are them?)
This seems to be a Phonon/xine bug. Reassigning
Comment 4 Dario Andres 2009-03-25 19:08:29 UTC 
No response. Marking as NEEDSINFO
Comment 5 Severin Stampler 2009-03-25 20:34:15 UTC 
Sorry for the late response, I kind of forgot about that issue lately.
The videos I tested that with are either mpeg or avi/XVid. I also tried it with the gstreamer backend for phonon, in that case the video player showing the preview doesn't even appear (this might be another bug?) so there is no such problem in this case.

Comment 9 Helio Chissini de Castro 2009-11-08 13:38:56 UTC 
I'm using now KDE 4..x svn and Phonon trunk, and can't reproduce issue.
In case of gstreamer backend, preview is only a slideshow of snapshots from video. The full video preview comes only from xine, so the problem relies in xine backend, but as i said i can't reproduce it here.
Can you confirm please ?

Thanks in advance

Closing for lack of feedback. Most likely fixed already.
