Comment # 4 on bug 1052793 from Antonio Larrosa

@Eric, could you try running this:

rpm -qi libqpdf13 cups-filters > packages_info.txt

and attach here the output file?

Also, after doing that, could you try installing the following libqpdf13 and
cups-filters-* packages?

(that's only one very long line with 5 urls after "zypper in")
Then run: sudo rccups restart

And check if that fixes anything?

That's basically a rebuild of the same packages you should already have
installed. So we're just finding out if this is related to Mageia-2016-0055 or
not (note I don't think so, since we don't include those patches on Leap).

@Fabian, I'll try to generate qt packages without the remote printer discovery
patch, but note that setting QT_DISABLE_PRINTER_DISCOVERY=1 should use the same
code as if the patch was disabled.
