There are two common reasons for that:
1. The file is open (under win32) and herefore you can't write it.
2. The permissions are actually wrong.

Both involves obvious solutions, but the second one is typically the result of
using different user accounts to access the same working copy. The first one
can also be caused by anti-virus software.

The typical cause is that some (broken) tool modified the content of the .svn
dir, like e.g. search'n'replace running amok. Since the files in there have a
different ending and are even write-protected, I'm actually willing to write
this off to a broken tool.

I have also seen this happen dues to some filesystem-level corruption which
made it impossible to access some dir. Running an extensive check/repair
fixed that though.

That's a lot. Up to now, I have still been able to trace all issues to either
misuse (by user or tool), misbehaving virus scanner or (as above) filesystem
