I wasn't able to get any useful information out of the stack trace.
Running addr2line does not show any functions. I'm not sure if this is
because you don't have the subversion-debuginfo package installed. I
would suggest you install this in case it makes a difference and the
failure happens again.

You did the right thing by reporting it, but I don't think there's
anything I can do if you can't reproduce the problem. Sorry.
