Systematic crash

Greetings,
I’m getting a systematic crash in Impress - see the attached screen shot. Does somebody have any idea what the culprit could be?

As I understand it the “osl::thread::create failed” message seems to relate to a user profile problem and/or incompatibility with an installed extension. If a reset of the user profile is unsuccessful, uninstall all extensions prior to upgrading.

Thanks, I try this strategy and keep my fingers crossed!
