Comment 40 for bug 115970

Hi, unfortunately i have similar problem.. Since i have installed new Ubuntu 10.04 (brand new installation) i cannot access VLC, QT_setting_utility, QT_designer, qBittorrent, and so on. Non of QT apps works except the application with their own qt library (NUKE, MAYA). I have already reinstalled QT many times but unsuccessfully.

qt4-designer:
my@me-laptop:~$ /usr/bin/designer-qt4: symbol lookup error: /usr/lib/libQtScript.so.4: undefined symbol: _ZN14QObjectPrivate15checkWindowRoleEv

VLC:
my@me-laptop:~$ VLC media player 1.0.6 Goldeneye
(it works to play film but without qtGui...)

my@me-laptop:~$ qbittorrent: symbol lookup error: /usr/lib/libQtGui.so.4: undefined symbol: _ZN14QObjectPrivate15checkWindowRoleEv
