It is certainly much more difficult to crash Thunar 1.6.10 with these 3 patches
applied.
1. #14 Harald's deactivate SEND_MOVED code paths
2. #41 Emil's reference counting to avoid crash in deferred reload
3. #65 John's don't call g_object_ref/unref on objects that are being finalized
Unfortunately, while running a release build with these 3 patches, Thunar will
still crash on rename and output the following messages:
(thunar:12326): GLib-GObject-WARNING **: instance of invalid non-instantiatable
type '(null)'
(thunar:12326): GLib-GObject-CRITICAL **: g_signal_handlers_destroy: assertion
'G_TYPE_CHECK_INSTANCE (instance)' failed
Segmentation fault (core dumped)
While running a debug build inside GDB, I was able to capture the following
stack trace which seems to correspond to the instance check failure and
resulting segmentation fault.
(thunar:27537): GLib-GObject-WARNING **: instance of invalid non-instantiatable
type '(null)'
Thread 71 "pool" received signal SIGTRAP, Trace/breakpoint trap.
