libxml2-2.7.4-1 which is available on test-update and rawhide seems to be broken preventing Inkscape to run. Should you attempt to dowgrade that package, make sure to downgrade packagekit, setroubleshoot and system-config-printer first, otherwise temporally remove them. Bug report has been submitted and hopefully should be fixed.
Busy weekend. I just took a break for making a presentation of Fedora Core 6 and Fedora Project for Vancouver Linux Users Group which will debut on November 20, 2006.

Should you be interested to view that event and live near Vancouver, here is the address .
