panel crash when changing screens

[Jasper Huijsmans]

Ok, I need help. I believe there is a bug report about this as well.

I'm testing this with Xnest, so that could be (part of) the problem.

The backtrace (see below) seems to indicate a problem with unrealizing 
gtk socket children, i.e. external plugins or systray icons.

Does anyone have a suggestion for how I would go about fixing this?
