Bug#982925: libgtk: print dialog lists autodetected printer twice

[Zack Weinberg]

Package: libgtk-3-0
Version: 3.24.24-1
Severity: normal

I have only one printer, a network-attached Brother HL model.  CUPS
autodetects it somehow and creates a queue for it:

$ lpstat -e
Brother_HL_L2350DW_series

This queue shows up twice in the GTK print dialog box, with two
slightly different names (see attached screenshot).

This is not merely a cosmetic problem: only one of the two queues
actually works.  If I select the wrong one, the print job disappears
into the aether.

According to https://github.com/apple/cups/issues/5017 it is probably
the print dialog box’s responsibility to determine that a single
queue has been reported twice (e.g. by cupsEnumDests()) and merge the
information from both reports.
