Garbage and utf8 arrors in pango

Everytime I open the printer dialog there is one printer for which the status line in the table keeps updating itself with garbage all the time.

As can be seen on the screenshot which i attached the status line shows strange boxes and cryptic characters. It also keeps updating on a high frequency (more than once per second) and everytime it changes it logs a message on the terminal like this:

(gedit:14079): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()

I can confirm that this bug is still present in a fairly recent version of gtk 3.5.x which i checked out from git a few days ago.

Sanitize memory handling in cups_request_printer_list_cb

gtk+ was trying to display already freed strings, leaking memory,
...I noticed this because I was getting weird blinking characters
as the status of my cups printers, and valgrind confirmed something
was wrong.
