The problem here is that the mime-type is only known by TSVN if it can
read it from a working copy.
The log dialog is a dialog that uses remote data, directly from the
repository. So it does not know about the working copy.
Reading the svn:mime-type property from the repository can take a few
seconds, and that's why that is not done. However without that
information, when doing the diff it doesn't even know the mime-type of
the file and therefore the specified diff tool is not used.

I will try and find a way to get the mime-type info remotely as well
without slowing down the whole diff command too much.
