Description Arvind S N 2003-08-27 06:00:41 UTC

When switching between workspaces using ctrl-Alt-Arrow keys, got this
dump. Not simulatable every time though

Probable fix

Comment 2 Arvind S N 2003-08-27 13:16:22 UTC

okay, that was bad try, the patch did not fix it :/

Comment 3 Arvind S N 2003-09-18 03:55:43 UTC

I think I got a reasonable way to simulate this while debugging
the panel.

Start the panel from command line, there is a small delay when panel
actually shows up. In the mean time start switching workspaces using
the keyboard quickly, metacity dumps.

One more attempt :)

Comment 5 Arvind S N 2003-09-18 04:40:30 UTC

in meta_workspace_activate_with_focus()a call to
meta_workspace_focus_default_window() is made with NULL as parameter
for MetaWindow. This seems to trigger the crash.

Comment 6 Havoc Pennington 2003-09-19 05:11:54 UTC

Discussed with Arvind, this is a possible dup of bug 122016

Comment 7 Arvind S N 2003-09-19 05:28:40 UTC

Rob's patch in bug 122016 fixes this crash too.
