git-svn "cannot lock ref" error during fetch

Hi all,

I'm new to git, and I'm experimenting with using git-svn to interact  
with a large SVN repository with lots of branches.

I initially did an init like this:

git-svn init -t tags -b branches -T trunk svn+ssh://server/svn/project

Then I did a git-svn fetch, which started pulling all the branches.  
After a while, however, it hit a branch that it couldn't pull:

Found branch parent: (tags/project-92~9)  
767f1f1601a4deae459c99ea6c1d1b9ba8f57a65
Following parent with do_update
...
Successfully followed parent
fatal: refs/remotes/tags/project-92~9: cannot lock the ref
update-ref -m r13726 refs/remotes/tags/project-92~9  
950638ff72acc278156a0d55baafbabb43f2b772: command returned error: 128

Some amount of searching failed to turn up any hints on what this  
error means or how I can work around it. I'd appreciate any advice ...

Is there a tag actually named "project-92~9"?  If so, it's
an invalid branch name for git.  I started working on a way
around it by mapping new names to it, but haven't gotten around to
finishing it....

fwiw: a similar error occurs when a svn tag-/branchname contains
spaces. The culprit seems to be $self->refname in

		command_noisy('update-ref', '-m', "r$rev",
		              $self->refname, $commit);

in rev_db_set()

unfortunately, there's more than one tag with this naming convention :(

 If so, it's

Aha! I don't really need 90% of the tags - is there a way I can tell  
the "git-svn fetch" not to bother with particular tags?

You can manually add fetch = foo:bar lines in the [svn-remote "svn"]
section of your .git/config file.  See the one for trunk.  Then
remove the tags= wildcard config line.

that worked really well, thanks a lot!
