I reused your tarball after adjusting configure.in so configure can work with my version of gtkmm. It compiled well and worked well. I then removed virtual inheritance. This time it gave me the same runtime warnings you mentioned. However my own version worked fine. I discovered that as I fixed the compile-time warnings of order of instantiation of base classes, this has also fixed the runtime behavior. The bottom line is just modify your class declaration so Glib::Object comes first!. You can even modify it in the header file alone, it will produce the compile-time warnings but it will work fine! Better is to modify both the declaration, and the instantiation order in the constructor to get rid of the compiler's warnings as well. By the way you don't get compiler warnings because you don't have -Wall in your AM_CXXFLAGS in Makefile.am.
