 Gwyddion, once open, will only allow for one attempt to open or save a
 file. Once the first attempt has been tried (successful or not) the next
 attempt will result in a blank loading/opening dialog screen. The program
 does not freeze but it shows no files to open and will not allow for
 saving. The cursors also becomes an hour glass with in the loading/opening
 screen. The two images attached show the before and after attempts to open
 files. There is also an error that occurs in the terminal when attempting
 to load or save, which is:

 (gwyddion:49914): GLib-GObject-CRITICAL **: g_object_unref: assertion
 `G_IS_OBJECT (object)' failed

 One last note, before posting this ticket, I tried to downgrade to
 versions 2.21 and 2.20. Neither of these versions fixed the issue.

 I've looked around on google and have not found a fix that has worked as
 of yet. Any help or guidance would be greatly appreciated.
