crash - linux/vm/recent cvs

redhat 6.1 was running vm under an xemacs that i had cvs'd and compiled last night (tues). I have been having trouble with crashes with betas the last week or so crashing with vm, once with gnus. I usually get not backtrace or error msg. So i was running this one under gdb I was composing a message, nothing fancy just typing. this was all the output in my xterm running gdb (gdb) run Starting program: /usr/local/bin/xemacs Warning: XtRemoveGrab asked to remove a widget not on the list Warning: XtRemoveGrab asked to remove a widget not on the list Warning: XtRemoveGrab asked to remove a widget not on the list Warning: XtRemoveGrab asked to remove a widget not on the list Warning: XtRemoveGrab asked to remove a widget not on the list Program received signal SIGSEGV, Segmentation fault. 0x8132fd9 in image_instance_parent_glyph (ii=0x9001598) at glyphs.c:1341 1341 if (IMAGE_INSTANCEP (IMAGE_INSTANCE_PARENT (ii))) (gdb) i get the XtRemoveGrab messages whenever i close a frame, i.e. send an email.
