What steps will reproduce the problem? 1. Created a new profile to be sure is not a problem with other plubins. 2. Installed the evoluspencil plugin 3. Start it

The application is terribly slow and unusable. I haven't the same effect on other configurations (PPC 64) just on Ubuntu 10.04 64bits. Adding an object takes about 20 seconds, make a resize puts the CUP (one of the 4) at 100%.
