foomatic-gui is not starting if foomatic-db-gutenprint is installed

Binary package hint: foomatic-db-gutenprint

If foomatic-db-gutenprint is installed the following is happening:

joe@ubuntu:~$ foomatic-gui
*** glibc detected *** double free or corruption (!prev): 0x08178838 ***
Unable to read printer database.

If I remove foomatic-db-gutenprint the foomatic-gui is working.

This is maybe not related to the bug described abowe.
My printer is not working, I dont know why. When I print it is just printing/feeding out empty pages. It has worked when I had the driver gimp-print-ijs.
In my Fedora-OS printing works and have driver gimp-print-ijs.
(Shall I do another bug-report for this ?)
