Bug#757271: Might need linking against qtDBus

[Lisandro Damián Nicanor Pérez Meyer <lisandro@debian.org>]

Package: libqt5bluetooth5
Version: 5.2.1-1
Severity: important

A user told me (not adding his identity in case he wants to preserve it):

thanks your for qtconnectivity package in 14.04 and putting it
into the ubuntu repository. I'm using the package to get a list
of bluetooth adapter from qt.

Unfortunately this does not work at all, which seems to make the
package a bit less usefull, than it could be 

The reason why its not working, is, that its somehow not
linked against Qt5DBus.

If I simply rebuild your package "debuild -us -uc" it works and is linked
against Qt5DBus:

>ldd ./debian/libqt5bluetooth5/usr/lib/x86_64-linux-gnu/libQt5Bluetooth.so.5.2.1

==> is not linked againt Qt5DBus, and does not work.

Qt5Bluetooth uses DBus to list for example bluetooth adaptors.
When I re-build your package I get:

warning: debian/libqt5bluetooth5/DEBIAN/symbols doesn't match
completely debian/libqt5bluetooth5.symbols and then some new DBus
related symbols:

>+ >_ZN28QBluetoothTransferReplyBluez7RequestERK15QDBusObjectPath@Base >5.2.1-1
>+ >_ZN28QBluetoothTransferReplyBluez8CompleteERK15QDBusObjectPath@Base >5.2.1-1
>+ >_ZN28QBluetoothTransferReplyBluez8ProgressERK15QDBusObjectPathy@Base >5.2.1-1


I have tested the btchat example against the default package, it does not
work. So I would say that the Qt5Bluetooth package does not work at
all on 14.04.
Simply rebuilding your package and install :

- libqt5bluetooth5_5.2.1-1_amd64.deb

fixed the problem for me.
