The bearer management plugin unnecessarily links against QtGui. The problem is that src\plugins\bearer\symbian\symbian.pri includes the following line:

QT += network

This is wrong because the QT variable by default contains 'core' and 'gui' so the correct line would be:

QT = core network

I verified using elftran -dump i that no symbols are imported from QtGui (at least on S^3) so we should remove this unneeded dependency.
