Version: (using Devel) Compiler: MinGW gcc 4.4.0 (emerge'd) OS: MS Windows Installed from: Compiled sources When building Qt in debug mode, it tries to link the debug version of libdbus-1 (called libdbus-1d). The dbus package from kde-windows.sf.net only provides a release build, however, which breaks emerging qt with EMERGE_BUILDTYPE=Debug. Proposed solution: Also include a debug build of the library in the dbus packages. There should be no legal issues with MinGW.
This has been fixed by forcing emerge users to build dbus in debug mode too.
