I am currently using gnome-open to open all files for which I do not know the default program (or can't remember it at the time).
With file extension .pdf
, gnome-open opens the file in my PDF document reader correctly, and then produces this message:
(evince:12416): Gtk-CRITICAL **: gtk_widget_show: assertion 'G TK_IS_WIDGET (widget)' failed
(evince:12416): Gtk-CRITICAL **: gtk_widget_show: assertion 'GTK_IS_WIDGET (widget)' failed
It's not a typo, it outputs the message twice. I do not know what a widget
is, but clearly this particular widget fails to check out as one.
With file extensions .jpg
, gnome-open opens the picture with the picture viewer, and then outputs this message:
(eog:12448): EOG-WARNING **: Failed to open file '/home/rhobot/.cache/thumbnails/normal/07915f2a54cfeb4b5f53aaa9c4988436.png': No such file or directory
I have a few questions:
1) Why does gnome-open work perfectly fine, yet simultaneously produce errors?
2) Why when opening a .jpg
file, which exists in /home/rhobot/Pictures
does gnome-open attempt to open a .png
file that exists in a hidden directory?
3) Most importantly - what do these error messages mean, and how can I fix my system so these errors do not occur?
Even though my files open, and the programs that they open with work just fine, I do not like the idea of my system not running as perfectly as it can. Please help me to diagnose and fix these problems. I am new to Ubuntu, please assume that I know nothing if answering.
