dpkg reporting some problems after last gtk upgrade

General problem with dpkg after upgrade.

# dpkg --configure -a
dpkg: ../../src/packages.c:221: process_queue: Assertion `dependtry <= 4' failed.
Aborted

I'm not able to do anything related to packages.

dpkg: error processing foomatic-filters (--configure):
