Package: libmediastreamer13 Version: 1:5.2.0+dfsg-1+b2 Severity: serious libmediastreamer12 and libmediastreamer13 both contain /usr/lib/x86_64-linux-gnu/mediastreamer/plugins/libmsqogl.so without declaring Replaces or Conflicts. This can result in unpack errors and is a serious bug.
Note that libmediastreamer12 and libmediastreamer13 should be coinstallable to make smooth upgrades work. Adding Breaks or Conflicts resolves the unpack error, but it breaks smooth upgrades. In reality, the file needs to be moved to an soname-dependent path or to a package that is not soname-dependent in order to not violate Debian policy. Helmut
