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

Just a small additional info: the start up flash screen shows "Starting Python", when it crashes.

I am not quite sure if this belongs here, but if you came here because you experienced the same bug and need to run QGis nonetheless: A workaround is to upgrade to nightly builds of QGis.
There is a repository for precise builds, see http://hub.qgis.org/projects/quantum-gis/wiki/Download
Works for me for now...

It turns out qgis was removed from Ubuntu 12.04 shortly before it was released. (Presumably due to this and other problems, see bug 935395 for details.) It was then re-added in Ubuntu 12.10 where it seems to run fine without any crashes. I therefore believe this can be closed since the package was removed from 12.04 making it impossible to trigger the issue there and it is working fine in newer releases.

If anyone want qgis in previous versions of Ubuntu, it might be possible to get it in via a backport. See instructions for "Requesting a Backport" at https://wiki.ubuntu.com/UbuntuBackports#Requesting_a_Backport for details.
