Looks OK from here:
http://git.trinitydesktop.org/cgit/
http://www.trinitydesktop.org/patches/

I am also doing a full test checkout from GIT for verification and have
not run into any errors so far.

That would cause problems, but I would suspect a haywire script or similar
on your end has simply deleted those directories.  Running "git submodule
init" and "git submodule update" from within the main tde/ directory
should restore those directories and reset your copy to the latest GIT
HEAD.

Please let me know if you run into any further issues; for obvious reasons
I am concerned at even the slightest hint that the main GIT repository
could possibly be corrupt!
