Mhmh, maybe the bug was fixed between 4.3.90.1 and 4.3.99.2. This would
be nice :) Or maybe the bug was in a panel plugin. Do you remember if
you had the same configuration at that time?

If it was, or if you can't remember, I'll assume the bug is fixed. If
not, we'll reassign to the plugin package.
