[issue3220] Exception in 2.1-rc when using MQ

[AlbertoGriggio]

New submission from AlbertoGriggio <alberto.griggio at gmail.com>:

I'm testing the 2.1 RC, and I'm getting the following traceback:

[alb at allblack mathsat5]$ HGPLAIN=1 hg qnew -f --git "p.patch"
transaction abort!
rollback completed

This happens on a repository with a patch queue containing 104 applied 
patches (using "hg qapplied | wc -l"), and 114 total patches ("hg qseries | 
wc -l"). The patches have been applied with Mercurial 2.0.1, if this 
information can help.

Unfortunately I can't share the repository, and so far I wasn't able to 
reproduce the bug on a "toy" repo. However, I'm willing to help as much as I 
can.
