I had assumed it was something to do with the C++ pre-main initialization. My current hypothesis is that it is to do with a Pango::FontDescription member that I have in a subclass of a Gtk::ListStore and the fact that I create a single static instance. I had tried replacing it with a Pango::FontDescription* to make the item primitive (not the right design but...) but I got the same error message which really baffled me. Hence the email. I am assuming the nth (where n is probably a single digit number) rule of GTKmm programming is "no static variables or members of static variables that are of some GTK based type unless they are contained in a procedure scope where the procedure is executed after the creation of the Gtk::Main or Gnome::Main object.". > A debugger (running with gtk applications with --g-fatal-errors gives > helpful stacktraces when there are gtk+ warnings) and or valgrind can > help. Thanks for the tip. I will give this a go. Is there a Web page or Wiki with these sorts of helpful tips that I have missed?
