Description

The data needed to reproduce this is private, so I can't post it here,
but the traceback looks like this:

   Traceback (most recent call last):

      in ?

      in _stabilize_directory
       if not entry_key[0] == '/':
   IndexError: string index out of range

This means that some directory node in the repository mirror tree had
empty string for an entry.  How did that happen?  Don't know yet;
first need to narrow down to the problem data, because the
reproduction recipe takes about half an hour to run :-).

I think there may be a second problem in the conversion, possibly
unrelated: it looks like some files are getting deleted from tags when
they shouldn't be.  An example is on line 1006018 of cvs2svn-dump,
where this path is deleted

   tags/blah_1_0_41_25/e/c/d/s/c/t/d/c/e/CSH.extension

...even though that tag is affixed to a non-deleted revision in the
corresponding CVS file.  (Note that "blah" is a secret word, and only
the first letter of each path component is given, etc, to protect
Daniel's company's privacy).
