I've tried to open or delete .jpg files in thunar and when I hover mouse over the .jpg file thunar crashes before I can right or left click. Its only with .jpg files as far as I can tell. don't think it's anything to do with the picture file because I can open mtpaint or shutter and they'll open from the menu. Below is the output from terminal when opening thunar:
(thunar:26633): GLib-GObject-WARNING **: Two different plugins tried to register 'TspPage'.
(thunar:26633): GLib-GObject-WARNING **: Two different plugins tried to register 'TspProvider'.
(thunar:26633): GLib-GObject-CRITICAL **: g_type_add_interface_dynamic: assertion `G_TYPE_IS_INSTANTIATABLE (instance_type)' failed
any help appreciated
