wnck-applet crashed with SIGSEGV in g_closure_invoke()

Binary package hint: gnome-panel

While Firefox was connecting to an internet site I right clicked the workspace selector and it crashed. I put it back on the panel OK.

I wanted to increase the number of workspaces to four but it crashed with this bug report. After re-installing the workspace selector I have been able to increase it to four. Firefow was trying to connect to a URL that was un-available.

This is my 1st bug report, I hope it helps you keep up the good work.
