Description Gabriel 2009-05-17 21:48:17 UTC 
Version:            (using KDE 4.2.3)
OS:                Linux
Installed from:    Unlisted Binary Package

I'm downloading a film and when I try to play it KTorrent crashes (not always, it's kind of random). The video uses the mkv container.

I'm on Arch Linux using their KDE packages. 

Application: KTorrent (ktorrent), signal SIGSEGV

If this crash is still an issue for you, could you please get a crash from ktorrent using gdb as described at http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_with_GDB please? Thank in advance.

Comment 7 Myriam Schweingruber 2010-02-09 23:27:36 UTC 
Dario, isn't this the same as bug 196320? At least the backtraces seem to indicate so, we should merge it with bug 196320 which already has a lot of dupes
Comment 8 Dario Andres 2010-02-10 12:29:40 UTC 
Backtraces seem a bit different, this one mentiones xine_open() and it has some other functions prior to the XIOError in thread1 (related to the PhononSeekSlider); while the other report doesn't contain this, and it is about xine_close()... I don't know, may be they all have the same root cause.
Comment 9 Myriam Schweingruber 2010-04-04 18:24:50 UTC 
Martin, any ideas?
