this is fixed now.

i tried this. it happens when mq extension is there, but not plain hg.

Is this still a problem for you? Otherwise set it to resolved, please.

It might be specific to the mq branch, in that case.

I can't reproduce this. I've tried with hgeditor, emacs, and vi.

What version of hg are you running ?
And can you post a full traceback please.

Thanks

If I save the commit comment without actually putting a comment in, I get an
exception which requires a recovery.  Normally I use this to cancel a commit
(because I changed my mind), so I'd want it to quietly abort the commit.

The exception is:
Exception exceptions.ImportError: 'No module named sys' in <bound method
transaction.__del__ of <mercurial.transaction.transaction instance at
0xb7e128ec>> ignored
