Build failure with Qt 5

[Stephen Kelly]

Hi,

A recent patch of mine makes the frameworks branch fail to build with Qt 5:

https://codereview.qt-project.org/#change,37624

I made it not possible to emit the aboutToQuit signal, which apparently 
KApplication tries to do.

I don't know the X code that KApplication is using which tries to emit that 
signal in response (iceIOErrorHandler).

Is that something that should be done in Qt itself?

Thanks,

Steve.
