On a 32- bit Intel system, the 12.04 (LTS) version of xpdf crashes.
Imho, there should be a fix for the LTS-version, but I would be
interested in workarounds (beside using evince or something) too.
Opening xpdf without any file works, but opening a file - any pdf-File -
and Segfault (isn't this a serious security issue? Shouldn't every
program be sanitized against segfaulting?).
Here is my strace-output:

I tried the hint, to deactivate some Chinese fonts. That didn't help.
