Hello all,
I'm having an issue with pdextended..
installed Lucid 10.04 (amd64 64-bit) ok on Ubuntu 10.10, starts ok w/ no error and loads all libs.
i was testing Gem with the builtin examples.
got stuck on 05.pix_effects.pd : i get a gui exit with segmentation fault as i try to activate any of the pix effect object..
i browsed the web for a solution ,but nothing..
here's the log if i start it from terminal:

aleclofabbro@aleclofabbro:~$ pdextended

and this is what i get on pd console, before it crashes
