I have been doing a lot of work with Inkscape and GIMP lately. When I try to open the image files from Nautilus, it sometimes hangs up. When that happens, the I can wait for a couple of hours for the "Nautilus Not Responding", "Force Quit or Cancel" screen to appear or turn the the power off and reboot. The keyboard and mouse are unresponsive when this happens.

At about the same time I started having the Nautilus problem, I began to get a pop-up window in the lower right corner of my screen periodically that tells me some software cannot connect. The details of this message are:

File '/repodata/repomd.xml' not found on medium 'http://download.opensuse.org/repositories/GNOME:/Factory/openSUSE_11.3/'

I do not know if the Nautilus problem and the repository message are related but they both started happening early this week.

Please Advise.
