Print dialog hangs on "Getting printer information" for CUPS browsed printer

[Christopher Barrington-Leigh]

I access printers via cups browsed.
I can print to them from the command line,

e.g.

lp -U myusername -d mcgill-mono -o sides=two-sided-long-edge $2 $3 $4 /tmp/myfile.ps

but from the system print dialog, they show up but are unusable.
If I click on one, the box just waits forever until I click Cancel, waiting for printer information.
