'library/ace' is not (re-)distributable
'library/ace' is full of pre-built minified blobs which are no different than pre-compiled binaries - not readable and not modifiable. On top of that there is no documentation, no license and not even link to the home page of the original project.
ace came from this repository then at least non-minified
src files should distributed. Minification is a bad idea and a potential source of bugs and security vulnerabilities. It is trivial to minify on build/install time if necessary.
FYI introducing Hubzilla to Debian (as an official Debian package) will not be possible with such outstanding problem.
