SIGSEGV encountered when closing the app

Hi,
My app is encountering a strange SIGSEGV bug, when closing it.
This is the generated info using the GNU Debugger (gdb) :Program received signal SIGSEGV, Segmentation fault.

Thanks for the help. -
It's quite impossible to help without knowing more details. It seems you've got some layout/widget hierarchy and at some point the deletion of some part of it fails. Might be a double-delete problem. Depends on how you create your widget and layouts, how you delete them and what are the relations.
A minimized reproducible code example would be best.
