Problem with git-svn

Hello,

I've been using git-svn for a couple of weeks now quite happily. Then the other day I decided to start using "git-clone -l ..." in order to create a few concurrent topic branches. I then moved to my canonical repository and did a "pull" from many of these topic branches.

So now I have a master git repository that reflects all of my accumulated work. I want to reflect this up to my subversion repository. However, it seems that doing all of that cloning and pulling has screwed up git-svn's tracking. I get this error now when I try to dcommit:

Unable to extract revision information from commit 865da18a70e8e93b1776864c73581198028e1190~1

The refid it's complaining about represents a pull of three changes from one of those topic branches:

commit 865da18a70e8e93b1776864c73581198028e1190
Merge: 42b0b95... f25fcef...
Author: John Wiegley <johnw@newartisans.com>
Date:   Thu May 3 00:17:17 2007 -0600

     Merge branch 'master' of /Users/johnw/src/ledger/master/

The refids that this refers to are also in my log, all with version information and log comments.

How do I get git-svn past this point? I can't find any command that will make it functional again. The last time this happened I just wiped my git repository and rebuilt it from scratch; but since people are tracking my git repository now, I'd rather now have to reset all of my refids (not to mention the sheer amount of time that it takes).

Thank you,
   John
