Package: qtbase5-dev
Version: 5.11.3+dfsg1-2+b1
Severity: important
User: debian-cross@lists.debian.org
Usertags: ftcbfs
Control: affects -1 + src:qtwayland-opensource-src

qtbase5-dev fails to coinstall with itself on any of pair of release
architectures. A typical error is:

| Unpacking qtbase5-dev:s390x (5.11.3+dfsg1-2+b1) ...
| Selecting previously unselected package qtbase5-dev:amd64.
| Preparing to unpack .../449-qtbase5-dev_5.11.3+dfsg1-2+b1_amd64.deb ...
| Unpacking qtbase5-dev:amd64 (5.11.3+dfsg1-2+b1) ...
| dpkg: error processing archive /tmp/apt-dpkg-install-o9TSE3/449-qtbase5-dev_5.11.3+dfsg1-2+b1_amd64.deb (--unpack):
|  trying to overwrite shared '/usr/share/qt5/doc/global/template/images/Qt-logo.png', which is different from other instances of package qtbase5-dev:amd64
| dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)

The multiarch hinter reports:

| qtbase5-dev conflicts on 4 files starting with /usr/share/qt5/doc/global/template/ on any two of amd64, arm64, armel, armhf, and 6 more

Running diffoscope on that file yields the following:

We cannot see this difference on the reproducible builds report, because
its output size is limited:
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/qtbase-opensource-src.html

I kinda would have expected dh-strip-nondetermnism to handle this as it
is supposed to clamp tIME chunks. Not sure why it doesn't.

In any case, the status quo is not valid usage of Multi-Arch. There are
essentially three options to fix this bug:

 * Remove Multi-Arch: same. (<- very bad)
 * Move the images to a Multi-Arch: foreign package.
 * Remove the variation of the tIME chunk. (<- preferred)

Due to the installation failure, the affected package(s) fail to cross
build from source.
