When I attempt to report the bug as described
above I end up on an Ubuntu page. Is that where
inkscape bugs are to be reported?
I installed Slackware previously to assist you and I solved the problem by installing the whole Slackware repository. I believe it's a dependency problem.
I no longer have the Slackware installation available, but if you do not solve this problem I might find time to configure the Slackware box again.
