Bug Description

I use openshot 1.4.3 from the bazaar repositories on Ubuntu 12.04. My melt version is 0.8.2.

Openshot crashes quite a lot when I press the play button or click on a timestamp in the timeline (in general when the preview window shall show something). Usually there is no information but this time it printed a backtrace:

*** glibc detected *** python: munmap_chunk(): invalid pointer: 0x00007f461c066960 ***

My first thought was to use the experimental Sunab PPA like he was
providing the 0.8.8 instead of the Stable Sunab PPA (which was having the
0.8.2 recently like yours version !).
But I 've just check and this one has the 0.8.8 that I advice you to update
your version of MLT again.

Keep your stable version of Openshot.
