Summary

0002489: Kdenlive (8.3) any rendering crashes

Description

Since two days it's impossible to render to any format and from any project, old ones or new ones.
Not a single format is working, I've tried them all. For the rest Kdenlive works nomally, only renderin crashes.
Kdenlive is updated to last version (8.3), so il MLT (0.7.7) and all libraries also. I'm working on Kubuntu 11.10 Kde ver 4.7.4.

Steps To Reproduce

Just send to render and process crashes.

Additional Information

launched Kdenlive from terminal, this is the result, maybe it could help.

crashes on any render

Notes
(0007841) j-b-m (administrator) 2012-01-30 21:03	A fix was just committed in MLT's git repository, it should be available in the next days in the sunab repository.

(0007910) leeps (reporter) 2012-03-01 12:21	Your patch from Jan 30th did not fix melt crashing for me: Using mlt 0.7.8 (Feb 15th), melt still segfaults at the end of the rendering process: melt[29597]: segfault at 7f10fb9889d0 ip 00007f11082a3da3 sp 00007ffff78b0cd0 error 4 in libpthread-2.13.so[7f110829b000+18000] Using threads=1 or threads=2, no difference. Could this be related? http://mltframework.org/gitweb/mlt.git?p=mltframework.org/mlt.git;a=commit;h=c00131c8cc53b85a993e222755cffd622f2b299f [^] If it helps, please let me know how to produce a stack trace for this, and I will. This makes 2-pass encoding impossible, because it crashes after finishing pass 1. Also, is there a tracking bug for this issue on mlt's sourceforge? I couldn't find one.
