Unusual GTK error message

[David Buchan <pdbuchan yahoo com>]

Background info: My program uses a file chooser dialog. I compiled it for the first time today on a 64-bit 
machine with Ubuntu 12.04 64-bit with gtk-3-dev. My program is run as root. I've been using it extensively on 
32-bit machine with libtgtk2.0-dev and Ubuntu 10.04 with no errors.

When I use the file chooser dialog, the following three errors appear on stdout:

(myprogram:2755): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', 
but failed: Failed to create file '/root/.local/share/recently-used.xbel.PLPWHW': No such file or directory

(myprogram:2755): Gtk-WARNING **: Attempting to set the permissions of 
`/root/.local/share/recently-used.xbel', but failed: No such file or directory

(myprogram:2755): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', 
but failed: Failed to create file '/root/.local/share/recently-used.xbel.5R5GHW': No such file or directory

(myprogram:2755): Gtk-WARNING **: Attempting to set the permissions of 
`/root/.local/share/recently-used.xbel', but failed: No such file or directory


Any ideas? A google search comes up completely dry (!! when did that happen last? weird) as does a Yahoo 
search. Dead end, it would seem. I'm certainly not at all keen to muck around in /root/.


Can this have something to do with running as root? It didn't throw errors for 32-bit with libgtk2.0-dev.
