git-svn throwing assertion on old svn tracking branch

hello guys,

it has been a while, i tried git in conjunction with svn... i got a nice history, when working with it. This Work is now a year old.

Now I wanted to get on working and got following error message while fetching from one specific svn tracking branch:

$ git-svn fetch -i svn_master perl: subversion/libsvn_subr/path.c:343: svn_path_remove_component: Assertion `is_canonical(path->data, path->len)' failed. Aborted

I checked the svn working copy, it is uptodate now (although i had to search for it, i havent been using this repository for one year...)

the output of gitk --all looks good, too. So i wonder if that error message above is only an alternative to say "more work? i ask because i am finished and have nothing else todo.."

It is only happening to this old repository...

Any help is appreciated. If possible, i would like to keep my development history for this repository.

I almost forgot, i use git version 1.4.4.3.g545b 

Sincerly Nicolas
