SIGSEGV crash in svn export with 1.2 under Debian

        Hi,

 It has been about since a month Subversion 1.2 was introduced in
 Debian unstable (sid). It seems I'm not the only Debian user victim of
 crashes in "svn export" since this new version, at least 3 persons are
 affected.

 I'm writing to this list to confirm I should open an issue in the
 tracker.

 The Debian bug is at <http://bugs.debian.org/314381>. It doesn't
 happen 100% of the time, since I tried upgrading again a couple of days
 ago, and I could do a couple of imports prior to crashing again.

 Branden Robinson offered core dump, ltrace, and strace in the bug
 report, I added a bt full of a debug rebuild of Subversion (-O0 -g).

 It starts like this:
Program received signal SIGSEGV, Segmentation fault.
