Of course, here, the current directory is the repository path, should have
made that more clear. :-)

I did not use any search-and-replace tools, so I think this can be
excluded. I even would say that nothing but svn touched these
directories. I also can't see any pattern in this behaviour. :(

From the strace of svn update I learned, that svn is opening .svn/log
right before the error occurs. Having a look at said file, it is missing
the first line, which should be

<?xml version="1.0" encoding="utf-8"?>

, right? The entries file has this line (although I remember also having
problems with corruptions of the entries file from time to time).

I attached a zipped .svn/log, hoping it gives you additional information.
