[Kdenlive-devel] Kdenlive always crashes on closure

[Harry van der Wolf]

Hi all,


My kdenlive versions always crash when I quit the program. I always use 
the file->quit option to close kdenlive nicely. Untill now I did not pay 
much attention to that as kdenlive is reasonably stable during use.  So 
I do not consider this high priority, but as jb is fixing things at high 
speed again I thought I mention it to the forum.
Maybe it is a very simple thing to fix, maybe it is something in my 
configuration.

This "bug report"  is valid for Kdenlive versions: 0.4 package from 
mediafire,  0.5SVN self compiled 04/02/2007, 0.5svn of 16/02/2007 and 
05.SVN from 17/02/2007 (16:00 CET) used on Kubuntu 6.10. My Kubuntu is 
at least twice a week updated/upgraded (apt-get update; apt-get upgrade).
Also using fluxbox, ICE-wm or ICEwm-lite as window manager doesn't make 
any difference (as expected, but you never know).


It always crashes with signal 11 (SIGSEGV).
It does not matter whether I:
- Start kdenlive and immediately quit
- Start kdenlive, open a project and quit.
- Start kdenlive, open a project, do some changes, do not save and quit.
- Start kdenlive, open a project, do some changes, save the changes and 
quit.
- Or work for half an hour (or so) and quit.

The kde crashhandler always gives me the following output

Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".

I hope this make sense to a programmer.
