I cannot reproduce :( when exactly does the crash happen ? is it enough to just open the application (without arguments) and close it immediatly ? does it also happen when using bespin style, with transparency turned on ? Also the crash reported by the backtrace 'should not' happen. The access to the widget that creates the crash is protected by a QWeakPointer (so one can't access an invalid widget); and should not happen either to a widget that have been deleted (because of an 'unregister' slot connected to the 'destroyed' signal of the widget. It is strange also that the crash happens 'as late as' widget::test_attribute. Still investigating though (but answer to the questions above would be welcome) best, Hugo
If you can provide the information requested in comment #1, please add it.
I ran it from Konsole, with no arguments. It crashes every time, no matter what else is running at the same time. ***@*** ~ % subtitlecomposer Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.
