gtk-window-decorator crashed with SIGSEGV in wnck_window_get_actions()

[Reiner Jung]

This might be a duplicate, but as it happened out of nowhere I report it.

I was working and toggling workspaces with the cursor keys (CTRL-ALT-*) when the crash dialog popped up. Beside the dialog, I did not encounter any misbehaving application. Only one evince window was without decor and the sidebar was sticky, but the latter happens often without any crashes.
