Joop,
I'm running:
20 July 2013
Build ID: C-C-T-F-C1.12.2
Using Ghostscript version 9.06
on Linux Mint 15.
Scribus frequently crashes with signal #11 when ungrouping a group of objects. So frequently that I need to save my work (if I only remember) before every ungroup operation I do to prevent data loss in case of a crash.
Is this a known problem? I can provide further information and quite easily reproduce this for any extra information anyone needs.
