What kind of clip (format, etc) were you trying to analyse? And which project profile?

I've tried several formats, several profiles, with and without proxy.
All clips play fine in clip monitor.

For example:
CLIP : DV PAL WideScreen (720x576, 16/9, 25i)

Hmm, I am wondering if maybe your MLT version is compiled without the "motion_est" filter that does the work. Can you tell me the output of this in a terminal:

melt -query filters | grep motion

I just fixed a possible crash when the filter does not work in MLT

Indeed, the motion estimation plugin isnt built.
If it does not build by default there may be really few users able to give clip analysis a try :-)

Sorry but I wont be able to give your fix a try until several days (hd crash, several blocks lost).

Thinking, maybe it would be better to disable Clip analysis if the plugin is missing.
