MyPaint @1.2.0: TypeError: GLib.filename_to_utf8() takes exactly 2 arguments (4 given)

I'm running MacPorts 2.3.4 on two Macs with German locale.

Error message when starting up:

Please ensure you've installed py27-pyobjc-cocoa by running:

sudo port install py27-pyobjc-cocoa

Replying to ryandesign@…: Both, py27-pyobjc-cocoa and py35-pyobjc-cocoa (just in case mypaint grabs the python3.5 executable) have been installed before. I uninstalled -f py27-pyobjc-cocoa and installed again. No change. Additional info: I'm using the +quartz build for everything on my system (no X11).

Please ensure you've installed py27-pyobjc-cocoa by running:

sudo port install py27-pyobjc-cocoa

This is a conflict with most recent glib 2.48, see this MyPaint issue at github:
​https://github.com/mypaint/mypaint/issues/634

Latest mypaint git master includes the fix as discussed in the mypaint issue and launches ok; the fix was also backported to the stable 1.2 branch (a new stable release is still pending though AFAIK).
