QT issue

[MWB]

Hello!

I have a problem with compiled applications like:
vyqchat 0.1.1 - Vyppres Chat (www.vypress.com) compatible 
client for Linux
Psi 0.9  - jabber client (psi.affinix.com)
Both compilated without any errors.

[cut]
[mwb at localhost mwb]$ vyqchat
vyqchat: relocation error: /usr/lib/qt-3.1/lib/libqt-mt.so.3: undefined
symbol: _ZN7QTabBarC1EP7QWidtPtPKc
[/cut]

[cut]
[mwb at localhost soft]$ psi &
[2] 4186
[mwb at localhost soft]$ psi: relocation error:
/usr/lib/qt-3.1/lib/libqt-mt.so.3: undefined symbol:
_ZN7QTabBarC1EP7QWidtPtPKc
[2]+  Exit 127                psi
[/cut]


It appears also in applications from rpms like:
imgSeek-0.8.2-1.i386.rpm

[cut]
Traceback (most recent call last):
  File "/usr/lib/python2.2/site-packages/imgSeekLib/ImgDB.py", line 51,
in ?
    import imgdb
ImportError: /usr/lib/qt-3.1/lib/libqt-mt.so.3: undefined symbol:
_ZN7QTabBarC1EP7QWidtPtPKc
[/cut]


[mwb at localhost soft]$ rpm -qa | grep qt
qt-MySQL-3.1.2-14
qt-3.1.2-14
qt-devel-3.1.2-14

I can't figure out what's wrong?
_ZN7QTabBarC1EP7QWidtPtPKc - this is something mysterious
for me ;)
