Hi!

have a crashing gem with pix_objects like pix_blur, pix_set, etc...
On Gem CVS from today 5th of june 2006, compiled against stock Debian 
libraries, on a testing system.
I disabled imagemagick to avoid strange hangups when loading wrong files 
as images.
I tried with an imagemagick-enabled-version of Gem and have the same 
crashes. And it also crashes with pix_sig2pix~.

regards, Peter
