Comment 7 for bug 813230

I can confirm this issue with 11.10

When starting the HPlip-toolbox, an empty window appears (only the window border) and the system becomes unresponsive. I haven't tried to produce a log file so far, but I found out that the X-server instance seems to require huge amounts of memory. The system RAM runs full and the system starts swapping.
The only way to get the system back to normal operation seems to be a reboot - or to kill the X-server.
