5.10 summary menubar broken on XEmacs

Hi Folks! The menubar in the summary buffer is broken on XEmacs[1] with Gnus 5.10.7. Trying to access any menu in the summary buffer with a mouse gives: "Unrecognized menu descriptor", t And for some reason, I can't produce a useful backtrace so I'm kinda stuck with trying to debug this. Can anyone shed any light? Other menubars seem to be unaffected... group buffer, server buffer, message buffer all are fine. Footnotes: [1] SXEmacs 22.1.2, XEmacs 21.4, and XEmacs 21.5 are affected. Apparently XEmacs 21.5 is worst as it is dumping core with this. SXEmacs and XEmacs 21.4 just give the error. -- |---<Steve Youngs>---------------<GnuPG KeyID: A94B3003>---| | Te audire no possum. | | Musa sapientum fixa est in aure. | |----------------------------------&lt;steve(a)youngs.au.com&gt;---|
