I am using this
application: kdenlive (0.9.6)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-52-generic x86_64
Distribution: Ubuntu 12.04.3 LTS

-- Information about the crash:
<In detail, tell us what you were doing when the application crashed.>

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Floating point exception
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
[Current thread is 1 (Thread 0x7f708a8a27c0 (LWP 9000))]

I do not provide the full backtrace here - but I would like to get suggestions on what to try out.

I can edit and all looks OK and other applikations are working fine - but when I press the renderkey is just crash.
I have tried uninstall and reinstall - but also the svn beta and the problem is the same so can't render out
any of my work normaly i can solve the problem but does other have the samme problem maybe ?

Best regards
From Copenhagen

Please post the full backtrace, within [code] tags.

Please check to see if you have a package similar in name to "qt-sapi" and if so, remove it. This is an accessibility plugin which has been known to cause crashes in all Qt based releases.

Thanks - now I am confussed about the new 13.04 installation so I tried to type qt-sapi inside synaptic to see if could find
qt-sapi - but you say similar name so can find anything with this name. But I did find qt-at-sapi and removed this and
YOU made me a very happy kdenlive user today again - this solved my problem now it can render again !

Not a problem. I was under the impression the qt-at-sapi issue had been corrected though - obviously it hasn't (The issue with it only affects Ubuntu derivate distributions).
