system-config-printer hangs halfway through

[Dan Kegel]

Did System Settings -> printers -> add -> find network printer, selected my printer, typed in my password... and it hung.

Rebooting and retrying gave same results.

Killing 3446 didn't help, something just retried the operation.

Killing install-printerdriver.py seemed to get things unstuck, showed me the "Choose Driver" dialog, was able to complete and print a test page.

No idea why dpkg was originally unhappy.

This may be a dup of bug 1307917.
