Hi Ronie, Esteban.

Ronie's suggestion in the form Esteban presented it helped.��
After implementing the fix I failed to crash my application any more.

Will anybody be so kind to explain me what actually happens and why the fix works?
It looks so innocent.

Cairo Surface is GCd if not kept while using it�� then your system go BOOM :P
that��s why we need to be sure it will not be disposed before it��s time (hence we kept it in the form that needs to be displayed).��

Well, this surely helps when you changing session(s). But doesn't helps when you crashing within a single session.
A smarter approach will be to recreate surface at attempt to use in new session, to avoid keeping copy of data around..
