confusing error message

[Airycat]

I;n trying to install Wallch on my mom's computer and get the following message.

File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 968, in simulate
trans.unauthenticated = self._simulate_helper(trans)
File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 1092, in _simulate_helper

File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 235, in required_download
pm.get_archives(fetcher, self._list, self._records)
SystemError: E:I wasn't able to locate a file for the ttf-mscorefonts-installer package. This might mean you need to manually fix this package.

I have no clue what to do

Also... I was wondering if it might be related... frequently the fonts on her screen are cut in half. "o's" look like carets, so do "n's". The problem comes and goes. Could it be connected to the above error message (caused by the same problem)? If not, I'll repost separately.
