Bug#788881: crash: meta_window_unmanage: assertion failed: (window->display->focus_window != window)

[Björn Weber]

Package: mutter
Version: 3.14.4-1~deb8u1
Severity: normal

Dear Maintainer,

when browsing an archive with file-roller, the mutter window manager crashes
and restarts. The crash is a result of the following error message:
mutter:ERROR:core/window.c:1323:meta_window_unmanage: assertion failed:
(window->display->focus_window != window)
x-session-manager[1362]: WARNING: Application 'gnome-shell.desktop' killed by
signal 6

I don't know if this is related to the crash, but there was also this inside
the system log (shortly after the crash):

I can't remember excactly but i think the crash happened when i switched to a
folder inside the archive.
Expected result: mutter should not crash.
