exported files are not of the selected revision

Hi All,

I see the following strange behaviour:

I have a repos with trunk/, branches/,tags/.
The latest revision is e.g 77 in trunk/
The latest revision in /branches/test is 75

Now I like to to export some revision from the repository
and open the Export dialog.
I enter the desired revision number e.g.76 and press Ok, however the mistake
I made was that I selected not /trunk but some
branch , e.g. branches/test123 as URL

Now the operation completes and says "Completed at revision 76".

However after checking the files, not revision 76 is exported but the
highest revision of the branch: 75.
To me it appears that exporting rev76 went Ok , but i ended up with rev75!
This can be very dangerous IMHO!

When I try to export a rev from /trunk which is above the HEAD (77 in my
case) then I get an error that the revision doesn't exist.
However i don't get any notification when making the above described mistake
of selecting the wrong URL.

using TSVN 1.4
