-- Information about the crash:
Multi-tabbed gnome terminal was running on Workspace 1 when I launched the appearance preference panel on Workspace 2. Doing that caused the gnome terminal crashed in Workspace 1. One can not also that I use 2 screens at the same time (laptop + external)

The crash does not seem to be reproducible.
