I ran across your post b/c I was looking for a solution for why my lastfm client stopped running with the same error you were having...
I fixed it and it was definitely caused by a third party app that installed an old version of libQt... in my cases nessus.. found it by typing: ldconfig -v saw: /opt/nessus/lib: libQtGui.so.4 -> libQtGui.so.4.3.4 libQtCore.so.4 -> libQtCore.so.4.3.4 libQtXml.so.4 -> libQtXml.so.4.3.4 realized the "installed" version is 4.4.0 to fix, removed /opt/nessus from /etc/ld.so.conf reran sudo ldconfig fixed!
