no... i'd say the problem is... somehow the app is being run in some limited
container with no permission to write to $HOME.

yes. that's it. you're going to have to un-limit ubuntu touch. elementary
expects its config in ~/.elementary/ ... eeze is expecting to also watch files
it cannot. efreet is expecting to talk to efreetd via a socket that is also
created (depends on env vars) ... but regardlwess of thigns in $HOPME it should
be able to load system config files from PREFIX/share/elementary for example...
has something gotten messed up here on efl install?

it's complex... and not programmatically. it highly depends what efl is looking
for - it loads system files and user files (user first - if not then system).
system locations will depend on where efl thinks its installed (it figures this
out at runtime via dlinfo etc.).
