thanks,
the newest Linux Mint only uses GTK 3.18. Seems this is the
problem.
Not happy that newest meld is not running on the most popular
linux distro.
Made a few tests:
1) Meld 3.18.0 is running on Linux Mint 18.3
2) last running commit of master is Commit 6f928ff9, the next
commit includes some changes to gtk 3.20 :'(

I think `set_css_name` is part of the theming
revamp in gtk 3.20. Make sure you have a recent version and that
it's getting picked up and not an older version when you run
from git.
