gnome-settings-daemon crashed with signal 5 in xkl_process_error()

[Sam_]

Did lots of workspace switching due to testing another bug. The last was testing available alt+tab keys. Again switching workspaces freezes workspace switcher, no mouse or shortcut worked. After a while apport dialog opened top left corner under the panel, but buttons to send the report were accessible. (Forgot to make a screenshot there.)

There have been other reports which are either closed, expired or fixed. (screenshot)
The newest Bug #825073 wasn't among them, it was found through searching bug reports.
Since bug triage Wiki says coredump needs to be removed first to make a report public I didn't make it a dupe yet.

Mmh, actually the system is up-to-date and I've followed suggestion #1 there creating an /etc/apt/sources.list.d/ddebs.list.
