Description Guillaume Desmottes 2010-07-08 08:25:31 UTC 
I have this crash when starting Empathy with GTK+3; no problem with GTK+2.

So what kind of GtkCellRenderer is cell here?  Own implementation or a cell renderer provided by GTK+?

That's a good question, I'm wondering the same... We have 3 custom renderer in empathy source code: EmpathyCellRendererActivatable (subclass of GtkCellRendererPixbuf, and does not override get_size), EmpathyCellRendererExpander and EmpathyCellRendererText (both subclass of GtkCellRenderer and does override get_size).

So our custom renderer should all be fine, I guess the problem comes from a gtk renderer.

Guillaume, could you please print the GType of the instance that does not have that get_size() virtual method? something like g_print ("%s\n", g_type_name((GType) instance)); just before the assert should do the trick.

Seems this crash was actually because of a memory corruption elsewhere. Closing it for now.
