Bug#911179: Qt5 packages uninstallable in Sid

[Jussi Pakkanen <jpakkane@gmail.com>]

Package: libqt5core5a
Version: 5.11.2+dfsg-3

Qt packages are currently uninstallable in Sid. Trying to do a
pbuilder package build from scratch gives the following error:

The following packages have unmet dependencies:
libqt5sensors5 : Depends: qtbase-abi-5-11-0 which is a virtual package
and is not provided by any available package

libqt5webchannel5 : Depends: qtbase-abi-5-11-0 which is a virtual
package and is not provided by any available package

libqt5webkit5 : Depends: qtbase-abi-5-11-0 which is a virtual package
and is not provided by any available package

                Depends: qtdeclarative-abi-5-11-0 which is a virtual
package and is not provided by any available package

qttools5-dev-tools : Depends: qtbase-abi-5-11-0 which is a virtual
package and is not provided by any available package

libqt5designer5 : Depends: qtbase-abi-5-11-0 which is a virtual
package and is not provided by any available package

libqt5positioning5 : Depends: qtbase-abi-5-11-0 which is a virtual
package and is not provided by any available package

This happens both on x86 and x86_64 and affects many packages.

Thanks,
