So I tried using text3d, and
it crashes pd if I try to use fullscreen. 
    

never encountered something like this (i have seen and run lot's of
installations with [text3d] in fullscreen)
are you sure it is related to [text3d], and not something else?
does fullscreen work in general?
does it still crash if you replace all the [text3d]s by a dummy
abstraction [textdummy] (inlet->outlet)?

Well [text2d] used to work in fullscreen, as well as [pix_image] -> [pix_texture] -> [rectangle]...

I running Ubuntu Karmic and Pd-0.42.5-extended20100111 (which I just
installed, but the problem was there in the previous version). My
graphics card is RV350 Mobility Radeon 9600 M10.
    

which driver do yo use?
I think the driver is the problem - after some googling I tried an ATI driver which really messed things up (no x server!). So I removed it and now it's broken all of Gem! I guess this is a xorg / xserver issue so not for this list perhaps, but if anyone can help, please let me know!!
