Gtk-WARNING **: Locale not supported by C library.

Running a fresh install of 10.10. Installed Banshee, it fails to run and gives me this:

Code:

(Banshee:1765): Gtk-WARNING **: Locale not supported by C library.

Running Devede throws something similar:

Code:

(process:2125): Gtk-WARNING **: Locale not supported by C library.
	Using the fallback 'C' locale.
DeVeDe 3.16.9

Traceback (most recent call last):
  File "/usr/bin/devede", line 138, in <module>

    return _setlocale(category, locale)
locale.Error: unsupported locale setting

Also, probably related: in nautilus, sorting by name is case sensitive. Meaning all files/folders beginning with uppercase letters appear before all files/folders beginning with lowercase letters. I found this thread about the same problem, but the solution doesn't apply to me because the line `export LC_COLLATE="C"` doesn't appear in my /etc/profile.
