Description David King 2014-03-16 22:00:14 UTC 
On current Rawhide, with control-center 3.11.91-1 and gnome-bluetooth 3.11.3-1, I get a crash when doing: system status menu->Bluetooth Settings->device which is "Not Setup". The crash occurs when the PIN confirmation dialog pops up on the N900. I do not think that is specific to the N9/N900, but I do not have any other Bluetooth devices to hand. There seems to be several retrace reports in Fedora:

https://retrace.fedoraproject.org/faf/problems/1535756/

It looks like a crash in gnome-bluetooth:

    settings: Fix crasher with latest GTK+
    
    The way to set headers for GtkDialogues changes, and setting
    our titlebar in _init() might cause the default GtkDialog implementation
    to overwrite our widget, eventually leading to free-after-use problems.
    
    Create the titlebar in constructed instead.
