messed up repo. can I recover?

[Michael Jay Lippert]

Hi,
I know the old tortoisehg 1.1.10 w/ hg 1.8.1 isn't really supported anymore, but I'm still using it.

I just did an mq pop from tortoisehg and then closed the explorer window.

And now I can't reopen the tortoisehg explorer window on that repository.

My hg repository now seems messed up.

hg status says "warning: ignoring unknown working parent 904462990da1!", and then lists a bunch of modified files.
hg log just returns "abort: 00changelog.i@904462990da1: no node!"

Is there a way to fix this repository? Even just removing this bogus node so that I may have lost the last changeset or 2 would be useful.

I'd like to know more for the future because I'm cloning a new repository, and I'll copy my mq patches over to it. But that's still more work and time than if I could quickly fix the broken repo.

Thanks,
Mike

This is the tortoisehg error when I try to open the explorer on this repo:

OK I think I just figured it out.
The problem was in the mq patches/status file. I just deleted the contents of that file, and things are ok again.

I then just have to update discarding any changes, and qpush the patches I want back.
