Bug#827896: libqt5gui5 uninstallable in multiarch due to dependency on mesa-utils

[Alessio Gaeta <alga777@gmail.com>]

Package: libqt5gui5
Version: 5.6.1+dfsg-2
Severity: important

Dear Maintainer,

trying to upgrade liqt5gui5 5.5.1+dfsg-17 -> libqt5gui5+dfsg-2 I get dependency
errors.

The problem arises because:

 - I have liqt5gui5 installed for both amd64 and i386 architectures

 - liqt5gui5:i386 depends on mesa-utils:i386

 - mesa-utils:i386 conflicts with mesa-utils:amd64, which is already installed
on my system

Reading the package changelog I found these entries (shortened):

 - qtbase-opensource-src (5.6.0+dfsg-2): Add mesa-utils as libqt5gui5 dep,
needed for Xsession.d script

 - qtbase-opensource-src (5.6.0+dfsg-3): Improve the Xsession.d script so it
won't fail if mesa-utils is not installed

So it seems that mesa-utils is not so essential after all. Moreover, it's not
clear to me why a library package should depend on an external utility.

Finally 'dpkg -L libqt5gui5:i386' gives me no reference at all to Xsession.d.

Thank you for your work and have a nice day
