[PD] GEM - pd 0.39 crashes with pix_movement + pix_blob

[altern]

hi all

yesterday i tested a GEM motion detection patch with a friends laptop to 
find that PD crashed really badly after few seconds. It looked to us 
like it crashed when there was big changes on the incoming data (sudden 
movement in front of the camera...).

The funny thing is that my friends laptop is a brand new Asus laptop 
running Vista and mine is an old IBM with XP. So the Asus should be much 
more powerful than mine... but there is no problem at all in mine with 
same patch.

We were using PD extended 0.39 on Vista, the camera is integrated, I 
could not check the type of graphics card and camera (no time sorry). 
Just noticed that there was no output on the PD console at all, just 
crashed.

We noticed that we could remove either pix_movement or pix_blob from the 
chain and then it would not crash. So it looked like the combination was 
problematic.

i know this is not very good description of the problem but does it ring 
any bell? thanks!
