$ LD_LIBRARY_PATH=/usr/lib/i386-linux-gnu/mesa skype

works as a workaround, seemingly proving it's an nvidia issue

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Gunnar Hjalmarsson (gunnarhj)]

Well, we know that

  Skype + Nvidia + qtwebkit-2.3 => Problems

There are other theories about what the root problem is. Some say it's qtwebkit-2.3, because downgrading to the Quantal version of libqtwebkit4 solves the problem too. Other say that Skype needs to be rebuilt against qtwebkit-2.3.

A workaround is about to be uploaded to the archive; see bug 1155327.
