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 and noticed it had an entry that said
UnreportableReason
You have some obsolete package versions installed.
and it mentioned python, python-minimal,python2.7,python2.7-minimal. Ubuntu update upgraded those packages this morning and the screen refresh is now working correctly in TeamViewer, so I will not be surprised if it also resolves the lsb_release errors, but I will have to wait for the next couple of days to see if it does indeed make those crashes go away.

[Impact]
SIGCHLD in lsb_release isn't handled correctly by Python causing the error code 10 IOError in some cases. Upstream Python has a fixed subprocess module, so switching from commands (where it is not fix) to subprocess (where it is fixed) should do the trick. Versions of lsb after precise are not affected because they use subprocess anyway, so this just backports that relatively mechanical change.
[Test Case]
Difficult to reproduce outside of teamviewer, but the following should work to verify that there is no regression: `lsb_release -a`
Also watch for no incidents involving the new package version at:
https://errors.ubuntu.com/problem/4eebfa6d3f91386f752207eeaf410b5a8ce81081
[Regression Potential]
If the patch to use subprocess is broken, then lsb_release may cease to work.
