I've got a similar problem.
I needed to install Python 2.6 (long story); doing so caused the cogwheel to vanish (and the "failed to start OAFIID: MATE_mintMenu; do you want to remove it?" message to appear at login).
Also the update manager disappeared from the lower right.
So I installed Python 2.7 from source; this didn't help. I verified that "python" resolves to Python 2.7.3. (which python ==> /usr/local/bin/python --> python2 --> python2.7.3 )
I eventually found I could add a menu to the bottom bar ("panel") - this isn't quite as convenient as the cogwheel, but I think, between the "main menu" and the "Mint menu", it shows all the same options. Notably, I can get to the Synaptic package manager again, and also the "Software Manager" (MintInstall 7.3.9). I tried reinstalling Python (2.7.3-Oubuntu2) from the synaptic package manager. it claimed success but awfully quickly, and noticed this within the Details:
"Waited for dpkg -assert-multi-arch but it wasn't there - dpkg Go (10: no child process)"
(When I select software in the Software Manager, it just freezes up and never does anything.)
I tried launching the Mate control center from the command line. I can see STDERR that way. "No module name pygtk" comes up when I click on Desktop Settings (which otherwise does nothing).
To sum up: I've got a working Python 2.7.3 installation; it's the default Python version, but some parts of MATE (cogwheel, update manager, desktop settings applet) are still not happy. Perhaps I need specific modules not included in the standard Python install.
If the package manager's not working, is there a quick way to reinstall the exact version/configuration/module set of Python 2.7 that I had before?
