This will help trying out visibility("protected"). There are two 
requirements:

1) setting protected only when building -- the importing is still 
"default"

2) it only works in "pure" texts: -fPIE, -fPIC, shared libraries (by 
extension, kdeinit and ioslaves). Otherwise, ELF mandates that global 
variables used by the application (e.g., QCoreApplication::self) be 
located in the application binary.

So far, I haven't managed yet to get past step #1.
