Package: libqtgui4
Version: 4:4.8.2+dfsg-11
Severity: normal
Tags: upstream patch
Qt's printing dialog (as used, for example, by Iceweasel) does not infer the
duplex setting from CUPS's printer options.
This is a known bug in Qt, see https://bugs.kde.org/180051.
A patch is available at http://bugsfiles.kde.org/attachment.cgi?id=41187.
We've been using this pĂatch for ages, I include a revised version for 4.8.2.

Version: 4:4.8.7+dfsg-20+rm
src:qt4-x11 was last released with Debian 10 (buster)
in July 2019 and has been removed from the Debian archive afterwards.
It has been superseded by newer versions.
See https://bugs.debian.org/953294 for details on the removal.
After regular security support for buster ended in August 2022 and LTS
support ended in June 2024, I'm closing the remaining bug reports now.
