As said before, this bug seems to be bound to the file dialog box, and on a brand new document, all menu items Save, Save as, Save and compress as well as Open must crash the application in your case. Is it right?

Absolutely no !

In file menu

New : OK
Open : Nok
Open recent files : OK
Save : Nok
Save as : Nok
Save and compress : OK

In Furniture menu
Import Furniture, choose : Nok
Import Furniture bib : Nok
Import Texture : choose picture : Nok

Option Create photo
Save : Nok

To understand better , we can write on french section. [:x]
