I've done a quick check against the qt lib from the package you are
using, and it's apparently wrong.  Your lib must somehow have gotten
corrupted.  

I would advise you to install the debsums package to check whether I
haven't made a mistake, and to reinstall qt if you get the same
results.  It's probably best to let debsums check the rest of your
files as well.  

Have you by any chance run the prelink program recently ?
