Inkscape 9.1 is troubled in the latest updates of the repos as per this post. Be careful.http://www.pclinuxos.com/forum/index.php?topic=57305.msg459721#msg459721
I'm always lagging in the updating of my system when it's working good knowing that problem do happen. Maybe that's why I still use PCLOS 2007 without even attempting to do the Big Update on my desktop. My laptop has the problem though and I can confirm it.
Lucky me, because I was getting ready to zero my drives on the desktop and install 9.1 and may have done it tomorrow, I'll wait.
