gnome-shell frozen and spinning in g_type_check_instance_cast() from meta_window_x11_is_focusable() from get_default_focus_window()

[Rocko]

This is a dump I created by killing a gnome-shell process that had frozen after trying to close a Java popup window; see also https://bugs.launchpad.net/bugs/1834984.

[Daniel van Vugt (vanvugt)]

The "spinning" part is from duplicate bug 1834984.

[Daniel van Vugt (vanvugt)]

But I am thinking this might be the same as bug 1834583.

[Rocko (rockorequin)]

Did launchpad auto-fill in the bug title? I don't remember typing in "spinning" or any of the rest of the text, but maybe I'm just going mad!

[Daniel van Vugt (vanvugt)]

I inserted the word spinning per comment #6 :)
