Yes, at least for this "feature".
The graying out of 'unrelated' paths in the log dialog is done by simply
comparing the paths. If a path is equal or below the path/url you chose
to show the log for, then it's considered related, otherwise it's
considered unrelated.

Technically, it would be possible to follow the history and even show
paths which got renamed as related. But that would cause big problems
when users commit changes to lots of files at once: the changed file
list can have hundreds of entries, and following the history of each of
those entries would bring even the latest and fastest computer to its knees.

A doubleclick on a modified path in the log dialog triggers the diff
function. It tries to fetch the file from the revision you've selected
and the revision before that one, so you can see what changed in the
selected revision. If the file was renamed in that revision, then the
file doesn't exist in the previous revision. That's why you get an
error. At least, you get an error with TSVN 1.3.x - it will work in
1.4.x when it gets released, because there are improved Subversion API's
available which can make this possible.

Hmmm - if you created the tag from your working copy and not directly on
the server, then the 'previous revision' is actually the working copy.
That could make even the 1.4.x Subversion API's fail (haven't tried, but
as far as I know the Subversion guys, they made even that work :) ).

To show a diff of a file, TSVN has to fetch the file twice, once for
each revision to diff. The Subversion API now has a param for a peg
revision (peg revision = revision to 'anchor' the url/path to). So with
that peg revision, it will work much better than before without it.
That said: TSVN can't really 'fix' all those cases where you want to
diff files from the changed files list (bottom of log dialog). Because
the url there has to be reconstruced 'manually' by TSVN. So there will
always be cases where it won't work.
But in 1.4.x, you can choose "show differences" from the top list of the
log dialog. It will then show you (reliable in 1.4.x, thanks to a new
Subversion API!) a list of changed files. If you doubleclick on those
entries in the list, it will always work.

P.S. I see from your mail address that you're working for leica
geosystems. Are you located in Heerbrugg? Maybe I should come by some
day (I live in Altstätten) :)
