'bzr: ERROR: Not a branch' on existing local branch. Can I repair it?

I just tried that and get the same error with the same output in the
log.  Writing to branch-name doesn't have any effect as you would
expect.

I have cygwin installed but I'm quite careful with my use of rm, and it
would be odd that I would execute such a command that would delete some
dirs in .bzr but leave others intact.  

Symantec Antivirus is on my machine, and it would be strange if it
deleted files in those two branches, but not others.

My repo resides on a shared drive and my dir on that drive has strict
quota limits.  I'm not sure if it was last week but I moved some large
files to that dir not knowing this and got a complaint ... not sure if
the quota management would arbitrarily delete files or not.  I suppose
it's possible that I was using bzr at the time, but I don't think so.  I
have a feeling that was later than last week, though.
