Well, I can re-create your error..

That's a horrible error message, and the reason for it is that no "gdb-4_18-branch" exists.

There's a _tag_ called "gdb-4_18", and there's a branch called "GDB_4_18", and they actually point to two _different_ commits (both "Initial creation of sourceware repository"). The commits actually have identical trees, but they're different, because they have different times - by 50 seconds.

Gaah.

Looking at cvsps output (from

	cvsps --norc -u -A -v -d --cvsdirect
		--root :pserver:anoncvs@sourceware.org:/cvs/src
		src > cvsps.out 2> cvsps.err

it's "PatchSet 104" (well, for me it is, I have a hacked cvsps, so it might not be that for you), which creates the "gdb-4_18-branch", but it appears that cvsps hasn't actually figured out any "Ancestor branch" for that commit.

What a crock.

Anyway, it's clearly a cvsps bug (mentioning a new branch without the _source_ of that branch). Equally clearly, "git cvsimport" is being an ass about then failing so totally on it.

I'll try to take a look at why cvsps does that.
