[PD] GEM error on latest pd extended with Ubuntu Gutsy

[altern]

hi

the video does not seem corrupted i can open it with VLC, no problem. I 
tried to find the reason for the error and I found that I can use the 
first frame but as soon as I go the the second or further it doesnt 
display it.

btw. passing mode 0 to pix_texture crashed PD. I was trying this to 
avoid the "gl invalid enumerant" problem i am getting on windows. I 
guess I might have to re construct my patch step by step to find the 
critical area. Bad because I dont have the time before the installation 
opening.

thanks

enrike
