thunar crashed with SIGSEGV

[David Kastrup]

Double-clicked on an SDcard icon (only mounted on-demand on my desktop). Works most of the time: this is a sporadic occurence.

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel Klauer (daniel.c.klauer)]

Same here when using Thunar to mount other partitions, seeing this right before crash:

(thunar:8364): Gtk-CRITICAL **: 00:09:37.161: ../../../../gtk/gtktreeview.c:6679 (validate_visible_area): assertion `has_child' failed.
There is a disparity between the internal view of the GtkTreeView,
and the GtkTreeModel. This generally means that the model has changed
without letting the view know. Any display from now on is likely to
be incorrect.
