It indeed is! Thank you!

Thanks to your work, we can see that this is a separate issue and not related to the one I reported in this ticket.

Program received signal SIGSEGV, Segmentation fault.

453    ../Source/WebCore/page/Page.cpp: Datei oder Verzeichnis nicht gefunden.

Could you please open a separate ticket for this. But more importantly, please contact the Ubuntu folks as it affects several of their programs.

This is the important backtrace of the Thread 1, “which caused the termination”.
