Heisenbug in the panel

I have a very strange heisenbug in the panel that cropped up all the
sudden like.

This is a svn snapshot of the "old panel" from about a month ago. I
right clicked on an item in the task list plugin, and seemed to hang
the desktop when I moused over the "send to" submenu, with the submenu
not filled in.

I suspected a possible race condition in netk somewhere, and the panel
seemed to have an unbreakable keyboard/mouse grab. I was able to
change VTs and I attached GDB to the panel process, but I'm too much
of a n00b to get anything useful from it. So I killed the panel.

Now when I start the panel I get a "Broken Pipe" error - possibly an
interaction with the session manager? I tried to start the panel under
GDB - and lo and behold, it worked! Ran it without GDB, and it didn't.

"This brings me back to a time where I had no worries. 
All I needed to do was watch Perfect Strangers."
