I tried to gather some profiling information. I took the most simple case: 
I start pan, and without doing anything, after a few seconds, I close it. 
It will take a very long time to quit.

You can download a 2.3 MB tarbal on which contains an strace of 
this process of more than 40 MB, and also a few gdb traces I gathered by 
running pan in gdb, and Ctrl-C'ing it several times after I quit. I hope 
this helps in identifying the problem.

I am running GNOME 2.19. I would not be surprised if this was related to 
the problem.
