SVN clients can't upload project to repository

The exact error both clients I've tried return is:

'Can't open file '/var/lib/subversion/beanstalk.storage/2578/sunshine/db/transactions/2-2.txn/next-ids': Permission denied'

I'm trying to do an initial upload of a Movable type installation and the client gets this error something like 2/3's of the way through adding the files.

I did wonder if its due to the size of the upload as Movable Type isn't exactly small and I've managed to upload a couple of other files.
