At this point, the program crashes. I am running (or failing to run) the latest version of SecondLife on
a fairly recent version of Fedora Core. I tried running the previous release of SecondLife on an ancient system a few weeks ago - if I remember correctly, the computer froze at the very point where this computer now crashes.

Any hints?

Oh, some additional information. Here are the interesting parts of my lastrun.log:
