================================================================
Dear Bug Team!
I was editing a buffer and appended a line of text to the file it was
displaying outside of XEmacs. I then attempted to revert the buffer
(which was almost certainly clean at that point--meaning I had no
unsaved edits on the XEmacs side), and XEmacs seemed to hang. I gave
it about two minutes to revert the buffer (the file is 148 bytes long
BTW) before killing XEmacs with "pkill xemacs", which produced the
below backtrace.
This bug is certainly non-critical; I'm just reporting it to be a good
beta tester. :)
I recommend assigning this bug to <stephen at xemacs.org>, mainly to
irritate him. ;)
