Segfault while opening/closing ComboBox menu, caused by NULL CssGadget
Last modified: 2018-05-02 18:57:37 UTC
I ran testcombo and started messing around opening/closing/browsing into submenus of the ComboBox that offers a list of species. The ultimate cause is trying to call get_preferred_size() on a NULL CssGadget. This may be related to submenus popping up/down quickly; I've not narrowed it down yet. That's made more difficult by the fact that apparently a failed ComboBox can retain a grab and not let me do anything else with my system without switching tty, logging in as root, and killing the test and gdb. Thread 1 "testcombo" received signal SIGSEGV, Segmentation fault. 0x00007ffff7575161 in gtk_css_gadget_get_visible (gadget=0x0) at /home/daniel/jhbuild/checkout/gnome/gtk+-3/gtk/gtkcssgadget.c:357 357 return gtk_css_node_get_visible (priv->node); (ins)(gdb) bt
