What could be the error?

[Szabolcs Ban <shooby kornel szif hu>]

 I wrote a gnome applet, what originaly from the fish, but the properties
 missing (I cutted out...) Everithyng is OK, but when I close (remove from
 panel) it kills my panel, the session gives this error:

** WARNING **: Forcefully removing connection 0x8153f40 from poll list
Saving to [/panel.d/Session-11c0a801f6000090267967200000007040000/]
Saving session: 1
** ERROR **: sigsegv caught

** WARNING **: GdkWindow 0x2c0001b unexpectedly destroyed

** ERROR **: BadWindow (invalid Window parameter)
  serial 1165 error_code 3 request_code 4 minor_code 0

 The code is ungly, so I did't include.. but if somebody wants to help, and
 this is not a "typical" error, I could show the code.. :]]]
