Description of problem:
Trying to run qtiplot gives the following error
qtiplot: symbol lookup error: /usr/lib/libQtSql.so.4: undefined symbol: _ZN14QOb
Version-Release number of selected component (if applicable):
qtiplot : 0.9-8.fc9.i386
Steps to Reproduce:
The problem is connected with extra software NessusClient which contains
some qt4 shared libraries which are loaded before the "fedora" ones.
Removing the NessusClient package or simply removing /opt/nessus/lib
from /etc/ld.so.conf.d fixe this problem.
