I've had exactly the same problem with broken menus, which appear to be due to libav's ffmpeg not handling the deprecated -loop_input option correctly.

This appears to be worked around in the latest devede (3.22, which is in quantal) by passing "-loop 1" to ffmpeg instead.

For me, installing devede 3.22 from quantal seems to fix the menu problem.
