nasty commit bug

From: Ben Collins-Sussman <sussman_at_collab.net>

Pilchie had to run off for a bit, but he's discovered some kind of
nasty bug:

  1. his commit segfaulted in post-commit processing

  2. he managed to commit a garbaged props.c file. (even though we
      have a checksum!)

These two problems may or may not be related. But before he vanished
from IRC, he printed a backtrace in gdb that indicated that problem #1
probably has something to do with the new libsvn_wc batons:

<pilchie> WTF
<pilchie> ?
<sussman> yes
<sussman> props.c is garbaged on the server now
* pilchie is confused.
<pilchie> AND has to leave for work.
<sussman> don't worry...
<pilchie> Can you revert that, and I'll try again later.
<sussman> we'll revert the change
<sussman> and figger out what's up
<sussman> wonder if your text-base is corrupted
<sussman> or something
<pilchie> Seems to be philips wc_baton thing.
<sussman> (though we have checksums for that!)
<pilchie> It's null in the bt.
