I booted Fedora 10 on the first machine and I can't repro the issue
there. However, it seemed that "gdmsetup" isn't available on Fedora.
However, after some fiddling I found out that I can also repro the bug
on the intrepid machine by repeated by running the command "strace
system-config-printer" and of course system-config-printer is indeed
available under Fedora. Even though the intrepid machine froze up after
running "strace system-config-printer" less than 20 times in a row, the
Fedora machine just keeps going even if I run it like over 30 times.
However, interestingly enough the Fedora machine reports that strace
crashes due to some memory corruption detected by glibc:
