It could, but not for *those* symbols. Exceptions require the typeinfo for the 
type being thrown (which is why cross-library exceptions sometimes fails with 
-fvisibility=hidden), but none of these types should be thrown:

QFocusHelper
QAbstractUndoItem
QStaticTextUserData
QItemEditorCreatorBase
QNetworkConfiguration

(some of those classes look like they came straight from classnamer.com)

To the OP: find out which .o requires those TI symbols.

Also, since I guess you're not using GCC, I can't rule out a compiler bug 
either.
