Why does acessing logs using "-r HEAD" doesn't provide results?

Hi all,

I'm having trouble understanding a problem with comparing paths in
WebSVN: Comparing two paths uses HEAD as revision specifier by default
and works in one setup and doesn't in another. The root cause is that
accessing the history of the repo simply doesn't provide any results
when used like the following:

> C:\[...]>svn log -r HEAD C:\[...]\trunk --xml --limit 1
> <?xml version="1.0" encoding="UTF-8"?>
> <log>
> </log>

Using the concrete revision number the working copy is in or some
different keyword works:

> C:\[...]>svn log -r COMMITTED C:\[...]\trunk --xml --limit 1
> <?xml version="1.0" encoding="UTF-8"?>
> <log>
> <logentry
> revision="667">
[...]
> </logentry>
> </log>

So why does HEAD doesn't provide any details? Thanks!

Mit freundlichen Grüßen,

Thorsten Schöning
