I have this very strange problem while compiling the project. MOC seems to be adding a namespace to the class name being moc'ed, although it's not mentioned anywhere in the file/class. The namespace, however, exists in a library which I use, but it's hidden far away in the header files and I don't use it in the UI files. This is what ...
