Thanks for the suggestion.

I'm not entirely sure what you mean by "Adjust the ref name if you
used a trunk/branches layout." - in what way do I need to adjust it?
Would something like "refs/remotes/trunk/git-svn" be right? At least
that ref corresponds with a file relative to the .git-folder.

Yes, I use a trunk/branches-layout... but I'm fetching a branch that
has been moved (multiple times), so git-svn seems to try to fetch
something called "trunk@54516"... perhaps the "@ 54516"

Anyway, I tried doing the following:

git update-ref refs/remotes/trunk/git-svn <SHA1 of old revision>
rm .git/svn
git svn fetch

git then outputs something like this:

r<some rev> = <some SHA1>
r<some rev> = <some SHA1>
...lots and lots of these...
r<some rev> = <some SHA1>
r<old revision> = <SHA1 of old revision>
r<some rev> = <some SHA1>
r<some rev> = <some SHA1>
...some more lines...
r<some rev> = <some SHA1>
Done rebuilding .git/svn/trunk@<some revision>/.rev_map.<some SHA1>
Incomplete data: Delta source ended unexpectedly at /home/erifay01/
libexec/git-core/git-svn line 4249

This is basically the same thing I'm getting if I just delete the .git/
svn-folder and re-fetch. For the record, I decided to roll-back about
10 more revisions than where I terminated, just to be sure.

This turns out to be a bit more tricky than I expected. You see, the
project has moved inside the repo multiple times during it's life-
time, and the revision where I broke the fetching is at an old
location.

So I tried fetching if from old location:
git svn init <old path> -s .
git svn fetch -r <old revision - 100>:<old revision + 100>

Doing the fetch outputs nothing (git svn init outputs "the usual
stuff", though). Trying to do the same thing with the new path (same
as above, but with <old path> set to the path of the new location)
gives the following output:

Path '<old path>' was probably deleted:
Filesystem has no item: REPORT request failed on '<new path>/!svn/bc/
<last rev>':
File not found: revision <last rev>, path '<old path>'

Will attempt to follow revisions r<old revision - 100> .. r<old
revision + 100> committed before the deletion

... And then nothing.

So, I'm still quite lost here. It might be that a full re-clone is
what is needed.
