David,

Thanks for the reply. Sorry for the confusion. 
I did actually test it now (and yesterday) with mgp 1.07a 
_and_ mgp 1.06a on Linux (Red Hat 6.2) and it still crashes. 
The reason I stayed with 1.06a was that 1.07a has another 
issue with transparancy that we are looking into now.

Removed the images below, but that has the same effect
(seg fault on t21, OK on t22)..

rpm comes from http://puchol.com/cpg/software/mgp/
I used the i686 rpm.

Peter
