Howto use StGit and git-svn at same time

Hi,

I'm a newbie and I'm using:
- git-svn to connect to a public SVN repo,
- StGit to manage my patches for the project hosted by this repo.

The current GIT repo was previously cloned from a GIT repo made with git-cvsimport. But the project moved to SVN, so I removed the GIT repo connected to the CVS.

I succesfully fetch the SVN, create a "work" local branch (connected to remotes/trunk), and create some patches. As the SVN evolved, I wish to retrieve info and update my patches.

So I tried a "stg pull" whihc failed because "origin" no more exists. So, I tried a "git-rebase remotes/trunk". Is it correct?

I'm actually unable to conclude, as the maintainer apply my patches with some improves, so I have to solve lots of conflicts. But I would appreciate if you can confirm me that the git-rebase is the good way to update a "workspace" managed both by git-svn and StGit.
