abrt 1.0.8 detected a crash.
Attached file: backtrace
cmdline: python /usr/bin/hp-toolbox
reason: Process /usr/bin/python was killed by signal 11 (SIGSEGV)
release: Fedora release 12 (Constantine)

Thank you for reporting this bug.
How reproducible is this problem? If you run the program from a terminal, is an error message printed?
What is the output of running the following command?
rpm -q hplip-gui cups-libs hplip-libs
Looking at the backtrace, it looks like the problem occurred in the program's single thread in fileno with a NULL pointer.
It looks like the openPPD was somehow called with a NULL file, and this led to the SIGSEGV.
Reassigning component from "python" to "hplip"; hopefully the hplip maintainer will be able to figure this out further or reassign as necessary.
If you need to track down exactly what is happening in the Python code, it may be possible to use this Fedora 13 feature:
by copying this file:
(assuming a 32-bit box like the one in this report) and regenerating the backtrace.
Note: this is segfaulting in the HPLIP Python extension for cups, not from pycups in system-config-printer-libs.

This should (I don't know how to reproduce) prevent hplip from crashing.
Here's a really easy way to trigger this:
>>> import cupsext
>>> cupsext.openPPD ('')
Basically any argument will work as long as it isn't a real queue name.
Reported upstream. Not sure whether they want the interface to return None there or raise an exception.
