No, please do not binNMU libgnomecanvasmm2.6 or gtkspellmm. They are very likely to need sourceful changes for the new std::string ABI (I haven't looked at these two specifically, but the rest of the glibmm stack has std::string in its ABI). It is correct that they are uninstallable: their ABI is not compatible with that of more recently-uploaded C++ packages. They will become installable when they transition to "v5" package names. I've done "GNOME team" uploads for a lot of the other glibmm-based packages recently, and will probably do these too if nobody else gets there first. S
