Wonderful, issue solved.

Another one solved.

Sounds like a point. However I don't know how large the converted
repository will be.

I fear that's not possible. Maybe we have somebody who has a super duper
fancy machine with lots of RAM and a huge number of cores. Currently it
takes 7 to 12 hours to create the dumpfile and ~8 hours to import the
dumpfile (http://wiki.php.net/svnmigration?s[]=subversion#the_real_run).
It would be interesting what machine was used there. Gwynne?
