unable to run tests requiring "updates=http://jlaska.fedorapeople.org/updates/traceback.img" option

[Andre Robatino]

Several tests in the install test matrix require the above option, but when
anaconda attempts to start after downloading the file, I get the text-based
traceback (not the expected GUI error) at

http://robatino.fedorapeople.org/traceback.xwd.gz

(use "display traceback.xwd.gz" to view, where display is part of the
ImageMagick package). The traceback is exactly the same with the i386 and x86_64
DVDs.
