bug#8705: 23.3; Emacs occasionally crashes (segfault) just after starting it

[Vincent Lefevre]

Emacs23 occasionally crashes (segmentation fault) just after starting
it. Here this was the first time with Emacs 23.3 (Debian's package).

All crashes of Emacs 22 and 23 I got occurred immediately after
starting it, and most of them (if not all) occurred either on an
XML file or when Emacs was started via svn to write a log message.

Here's a backtrace:
