Update: as it appears, this is a problem with how Subversion passes
the progress information to the clients. Depending on the ra_ layer
(neon, serf, svn) subversion sometimes uses more than one session
(connection) to the repository. If that happens (usually during
merges), the information passed to the client is undefined because the
client does not know that the information comes from two (or more)
different sessions.

I have to discuss this with the Subversion developers to find a
solution. Not sure how I can fix this...
