This symbol was added in Qt 4.5. That means you built your application for use 
with Qt 4.5, but you're running it against Qt 4.4 or earlier.

That cannot work.

You have to either upgrade all your machines to use Qt 4.5 or you must compile 
your application with an earlier version of Qt. (You don't have to downgrade 
the system Qt for that. Technically speaking, you don't even need to compile 
Qt 4.4: you just need its headers and you can link against the Qt 4.5 
libraries)
