[raman_31181]

Hello,
I have been working on Qt4 Designer for some days now.Today I encountered a strange problem.The Qt Designer window just doesnt appear when I try to open this tool.I tried through KMenu->Development->Qt4 Designer but the result is the same.I tried through Konsole and get the follwoing error:

[root@localhost mywidgetplugin]# designer-qt4
/usr/lib/qt4/bin/designer-qt4: error while loading shared libraries: libts-0.0.so.0: cannot open shared object file: No such file or directory

[root@localhost mywidgetplugin]# designer-qt4
/usr/lib/qt4/bin/designer-qt4: error while loading shared libraries: libts-0.0.so.0: cannot open shared object file: No such file or directory

Any ideas anyone?
