hi, my xemacs 21.4.3 (-O2 -march=i686) is crashing in gnus when i want to save some attachment (trough mouse menu->save). Unfortunately I can't track this problem because after compiling with -g -O0 it doesn't want to crash :-( It just displays: Warning: XtRemoveGrab asked to remove a widget not on the list I checked 21.4 cvs branch (release-21.4) but I didn't find any fixes (moreover there is no changes at all comparing to .3 release, strange). And I tried 21.5 (cvs version from today) and here problem occur, too but now I have backtrace (below). Patch fixing this *is welcome*.
