Comment 8 for bug 1744722

I am not very familiar with the Python language (prefer C/C++). It seems file versions we are using are little bit different (lines I suppose You mean, are shifted little up). That's why I attach my version here.
I suppose the wrong value sits in 'entry.dist' field. With method "self.sources.add(entry.type, uri, entry.dist, entry.comps, comment)", erroneous value goes to take effect. Is it possible to insert one line just before noted method call and there to set correct value (just temporary as workaround)? Something like 'entry.dist = "artful"'?
Can I rely that if this don't help me, at least will not disturb current installation?
