This may be a teamviewer problem. I don't know if it is relevant, but when
searching /var/log for any mention of munmap, I got the following results:
dvs4@dvs4-E6540:/var/log$ sudo grep -R munmap *
auth.log:Dec 7 08:31:22 dvs4-E6540 sudo: dvs4 : TTY=pt
I also have the problem of not seeing the Update Manager window when it
first starts up, and I found if I click the icon in the tray once it
does nothing visible but if I click the icon again the window appears as
it should.

Referencing comment #77, while updating the mentioned python packages
did correct some of the weird problems in TeamViwer itself (so it was
worth doing) it did not correct the lsb_release errors. I did install
the precise-proposed changes as per brian-murray, and the errors have
indeed disappeared
I had also received the crash reports each day after installing TeamViewer 8
under Ubuntu 12.04. I had also seen a couple of problems with the way
TeamViewer was not updating screens correctly on the client. Today, I happened
to look farther down the details screen on the crash reporter screen
I have a 12.04 installation that was upgraded from 10.10 to 11.04 to
11.10 to 12.04 using the update manager and then enabling Gnome Classic.
I had the same problem of alt+tab not working even though my
System Settings-> Keyboard> Shortcuts:---> Navigation
setting said Alt+Tab
