FBReader crashed with SIGSEGV in DBusMenuExporter::setStatus()

Trying to access the non-existent app menu causes the segfault; eg by pressing "Alt", or mouse-overing the app menu area.

Update: it's whenever I press "Alt" to try and get to the menu. I guess it has something to do with the global app menu.
