I was using one of the latest build's of pd-extended and have now 
updated it to 0-42.5-extended-20100126 which has Gem 0.92.2. I also 
tried Pd-0.41.4-extended-ubuntu-hardy-i386.deb from puredata.info but 
the problem was the same in all these versions. When I looked closer at 
the backtrace I assumed that maybe I had some library missing so I 
installed imagemagick via synaptic - although perhaps it just upgraded 
the version, or as you say forced the the ati-driver to use libstdc++. 
However, this seems to have fixed things, and I can now load images in 
pix_multiimage and pix_imageInPlace.

thanks
