Hi, Seems as if it (libqt4-dev) should also depend on libglib2.0-dev, apparently due to the fact that "Qt 4.2 now contains support for the Glib eventloop". At least one Qt4 app I've written needs libglib2.0-dev in the build-depends now as libqt4-dev doesn't depend on it, and that app is a pure Qt app, so the glib dependency comes from Qt.
