No solution from me, but I have the same issues with the static .tar.
Solution:
cd into otrdecoder-bin-i686-pc-linux-gnu-static-0.4.593
and run
python2 otrdecoder-gui
it works fine for me.
Import gtk is no longer supportet in python3. On my manjaro system python3 is set as default python...
I intvestegate a little bit more. The gtk implementation is complet rewritten in python3.
The whole script has to be rewritten to work with python3... I try the buildin 2to3 tool from python3 with no sucsess.
