[Bug 340252] [NEW] qt4 libraries do not work due to unknown symbol

[Jimmy Happy]

Public bug reported:

I am currently using Ubuntu 8.04 LTS. (8.04.2 to be exact!)

NONE of my QT apps are working at all! 
Many complain about a symbol error:
smplayer: symbol lookup error: /usr/lib/libQtNetwork.so.4: undefined symbol: _ZN14QObjectPrivate15checkWindowRoleEv

The symbol "seems" to exist, but as said, is undefined:
arthur at arthur-PC:~$ objdump -T /usr/lib/libQtNetwork.so.4 | grep _ZN14QObjectPrivate15checkWindowRoleEv
00000000      DF *UND*	00000005              _ZN14QObjectPrivate15checkWindowRoleEv
arthur at arthur-PC:~$ strings /usr/lib/libQtNetwork.so.4 | grep _ZN14QObjectPrivate15checkWindowRoleEv
_ZN14QObjectPrivate15checkWindowRoleEv

Package (general): qt4-x11
Version info  (executing dpkg -l | grep ii | grep libqt4):
ii  libqt4-core                                4.3.4-0ubuntu3                                       Qt 4 core non-GUI functionality runtime library
ii  libqt4-dev                                 4.3.4-0ubuntu3                                       Qt 4 development files
ii  libqt4-gui                                 4.3.4-0ubuntu3                                       Qt 4 core GUI functionality runtime library
ii  libqt4-qt3support                          4.3.4-0ubuntu3                                       Qt 3 compatibility library for Qt 4
ii  libqt4-sql                                 4.3.4-0ubuntu3                                       Qt 4 SQL database module

A sample program using QT is smplayer.
Dependency links (using ldd `which smplayer` | grep libQt):
	libQtGui.so.4 => /usr/lib/libQtGui.so.4 (0xb7782000)
	libQtNetwork.so.4 => /usr/lib/libQtNetwork.so.4 (0xb76f1000)
	libQtCore.so.4 => /usr/lib/libQtCore.so.4 (0xb753b000)

There was a bug about mixing QT libraries, but this isn't one of them.
There are NO FOREIGN INSTALLATIONS OF QT. (nessus is common, skype is another)
