I had similar problems when my repository was offline. 

I think/guess the command chokes when it receives some byte on the stdout.
Are you sure that nothing goes to the stderr if you type something like
$ svn log --xml --verbose --non-interactive --limit=10 \
http://svn.tuebingen.mpg.de/shogun 1>/tmp/svn.log 2>/tmp/svn.err
Is after this command svn.err really empty?

Or can you narrow down the search by adding some log.msg to
buildbot/changes/svnpoller.py?

Does it also work if you execute it also under the "buildbot" user
account/shell?

Best regards
