segfault in http-push

[Bob Copeland <me@bobcopeland.com>]

Hi,

With 1.4.5.2, I see this whenever I try to push a new branch over http:

$ git-push hash long_ids
Fetching remote heads...
  refs/
  refs/heads/
  refs/tags/
  refs/remotes/
updating 'refs/heads/long_ids'
  from 0000000000000000000000000000000000000000
  to   b24938890f04f3ba42b88f56f3ff2bbe0fda6629
    sending 10200 objects
    done
Updating remote server info
error: http-push died with strange error
error: failed to push to 'https://user@machine/foo.git/'

Here's a backtrace:

#0  0xb7cbd583 in strlen () from /lib/tls/i686/cmov/libc.so.6

) at http-push.c:2421

Error is at:
520             request->url = xmalloc(strlen(remote->url) +
521                                    strlen(request->lock->token) + 51);

(gdb) p request->lock
$1 = (struct remote_lock *) 0x80e7d40
(gdb) p request->lock->token
$2 = 0x65707954 <Address 0x65707954 out of bounds>

If I go fix up the remote repository I can usually get it to work.  
Any thoughts?
