Thanks for answer, Kjell. Yes, I've been using gdb, and seen place of the error message. For now there is no way to "override" property even using C code. One thing is good - that happens only once, when my custom widget GType is registered.
Well, actually, I am trying to port our business application from GTKMM-2.4 (2.10.10) to GTKMM-3.0. I have datetime widget - custom widget that I've derived from EventBox and CellEditable. EventBox should catch events, and CellEditable interface I've needed to create such widget in override for CellRendererText::start_editing_vfunc. Inside I've packed Entry (to edit datetime) and Button (to popup calendar). I guess, I should redesign widget now, to use GTK-3.0 Entry abilities, and derive direct from Entry widget. But, I have to say, that it's not so good, that GTKMM-3.0 is not supporting all features that GTK-3.0 brings now. It looks that there are few places left in the GTKMM code that should be redesigned using new GTK-3.0 features. I will be trying to do my best to find such places and report it here during port of our business application.
