What actually happens depends on children of the second dialog shell, i.e.
	when this shell has SelectionBox as it's child, and the List in
	selection box contains 0 or 1 items, everything works great, but
	when the list contains 2 (or more) items, any attempt to destroy
	first and/or second shell results in above error, with a stack trace
	looking like this:

*t
_XtDefaultErrorMsg(0x800575a0,0x800575b0,0x800575cc,0x800575dc,0,0)
XtErrorMsg()
XtWidgetToApplicationContext(0x80d9320)
XtRemoveAllCallbacks(0x80d9320,0x80a3ee4)
Destroy(0x80e5068)
Phase2Destroy(0x80e5068)
Recursive(0x80e5068,0x80041d6c)
Recursive(0x80d70ac,0x80041d6c)
Recursive(0x80e2f8c,0x80041d6c)
Recursive(0x80db8ac,0x80041d6c)
Recursive(0x80d81ac,0x80041d6c)
XtPhase2Destroy(0x80d81ac,0,0)
_XtCallCallbacks(0x8047c88,0)
XtDispatchEvent(0x8047ca0)
XtAppMainLoop(0x80b2c8c)
XtMainLoop()
main(argc=1,argv=0x8047df4,0x8047dfc)   [main.c:98]
_start()
*


If the second dialog shell doesn't contain List, no errors ...

Any ideas/suggestions ?
