Canon 6650 CUPS debug: failed to DeleteDevice: org.freedesktop.DBus.Error.InvalidArgs:Type of message, `(s)', does not match expected type `(o)'

[Dave]

CUPS output using command line (lp) produces nearly full black page output.  (Solid black field).  Output using evince or libreoffice is ok.

64 bit drivers provided by Canon were RPM only, so they were converted to .deb with alien.  This went normally.  I can print with evince and libreoffice without issue.  Printing from command line (lp filename.pdf) will produce the error whereas printing from a pdf GUI app (same file) will print ok.

I've turned on CUPS debugging and output the debug log here:
{removed link to avoid filter} pastebin.ca/2315773

The suspicious section, to me, is:
D [19/Feb/2013:14:15:13 -0800] Loading printer Canon_6650...
D [19/Feb/2013:14:15:13 -0800] load_ppd: Loading /var/cache/cups/Canon_6650.data...
D [19/Feb/2013:14:15:13 -0800] Calling DeleteDevice(cups-Canon_6650)
D [19/Feb/2013:14:15:13 -0800] failed to DeleteDevice: org.freedesktop.DBus.Error.InvalidArgs:Type of message, `(s)', does not match expected type `(o)'

Also, prior to setting debug, the error was:
failed to CreateProfile: org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon_LBP6650-Gray..' already exists

Thanks for any suggestions.
