Emacs hangs enabling debug-on-error

[Robert Mecklenburg]

This is from a fresh build on 2004-04-30 8am MDT.

When I enable debug-on-error from the Options menu I immediately get a
new backtrace window with a one line stack trace and emacs hangs.  The
call stack from gdb is shown below.  This does not appear to happen in
a freshly started emacs, only after I've been running for a while.
