There is also the GNOME_DISABLE_CRASH_DIALOG environment variable, so you
can avoid the annoying dialog while debugging. (This will leave crash
handling to the default handlers, which just dump core.)

However, you would be a lot better off just using gdb to attach to the
process and catching the crash in the act.

When you make binary-incompatible changes, you need to recompile everything
that depends on that structure.

If you don't want to rebuild things, instead of putting something in the
struct, you probably should just use object data and a couple of accessor
