Feisty: KDE System Settings crashed after installing 'foomatic-db-gutenprint' and rebuilding database (backtrace attached)

Binary package hint: kde-systemsettings

I wanted to add an Epson CX3810 printer but it wasn't listed (I wish there was a button to 'Add More Drivers?' and automate the install of 'foomatic-db-gutenprint') Anyways, I added the package and restarted the Add Printer wizard, which had to rebuild the driver database. KDE System Settings crashed when the database was done being rebuilt. The printer was available to add after the crash.
