"RA layer request failed: REPORT request failed" during git-svn
For what it's worth, I fixed it by switching from cloning from secure HTTP (from SourceForge) to regular HTTP. So instead of cloning https://... I cloned http://. No problems after that.
I had the same error message with a different project (after 50000 revisions). For me it helped to tidy up the git repository and then continue fetching from svn:
$ git gc
$ git svn fetch
Revision 12 and hence 13, 14 are messed up ( someone added a branch trunk in branches, but later deleted it, and that confuses git-svn). You might want to do:
git svn clone -r 1:11 --stdlayout https://wtorrent-project.googlecode.com/svn/ wtorrent-git
cd wtorrent-git
git svn fetch -r 15:HEAD
