Well i know about this....but there is not actual enigma 2 code. Only the python part is there. To fix something more fundamental enigma2 code (c code) is needed.
And what bugs do you struggle with? maybe you can list them 
Yes i can name some of....
1. Lack of EPG age rating so to be possible to use parental control efficiently (need age rating and genre to be possible to be got from EPG entry)
2. Sometimes EPG get lost
3. HBBTV cause entire system locking or not open at all on some channels (ex. RTL2 HD on 19.2E)
4. When using FULLHD skin and you do fast actions (ex. fast scrolling in a list) there are many artifacts, lags and you can see how the text got blurred. That generally happens if the background is pretty dark (gray for example) and text is white. I suppose this could be a driver issue or based on latest enigma changes for graphics loading.
5. PIG component in skins cause flickering on window close since for some reason it moves its position abnormally (that is clearly visible if there are no animations enabled)
There are other issues but that are the most issues bothering me
