preview blank

Bug Description

When I start a new project and add my video files the preview works.

Once I get to maybe 7 or 8 clips added into the timeline, it will no longer show the preview in the preview window (it is black) but the audio plays.

I have tried installing from apt and from source.

Once the preview stops working in the project it stops for good regardless of reopening the same project file.

Debian Squeeze 64-bit
Linux ns2.shawnread.ca 3.2.0-4-amd64 #1 SMP Debian 3.2.63-2+deb7u1 x86_64 GNU/Linux

apt, debs, and source

No LADSPA plugins were found!
Check your LADSPA_PATH environment variable.

The last version of MLT (i.e. libmlt, melt,...) are in the version 0.9.2.
However, yours are in the 0.8.0.
