Hi Alan,
I have used the debian out of the box version 5.1.0. I will try to reproduce (hopefully not though) the segfaults with the latest git release. Maybe its already fixed with the plbuf changes ... I will report the results then! Cheers, Peter > > > We take memory management errors (which often produce segfaults) > seriously.
