crash on hg qpush

[Nico Mahlo]

I downloaded Mercurial yesterday to give it a try. While testing MQ I ran into 
the following crash:

==================================================
$ hg qpush saft.patch
applying saft.patch
Unable to read saft.patch
** unknown exception encountered, details follow

==================================================

I don't know whether this bug report is helpful or not -- in any case I'll 
include a TGZ of the complete repository and a session.txt in zipped form 
containing my _whole_ session (about 2500 lines).

So if the traceback does not help, maybe you can gain some info from that 
session file.

HTH
