[Ulrik Sverdrup]

Package: mypaint
Version: 1.2.0-1.1+b2
Severity: important

Dear Maintainer,

mypaint does not start, output is:

INFO: mypaint: Installation layout: conventional POSIX-like structure with prefix u'/usr'
INFO: lib.i18n: POSIX: LANG='sv_SE.utf8'
INFO: lib.i18n: POSIX: LANGUAGE=None

    ustring = GLib.filename_to_utf8(opsysstring, -1, 0, 0)
TypeError: GLib.filename_to_utf8() takes exactly 2 arguments (4 given)

Since it mentions locale and utf8 for some reason, I also confirmed it
behaves the same with LANG=C.
