Shareaza

Sometimes after a crash G2 cache becomes empty and although G2 is selected it won't connect to any hub.

How often is sometimes? Anyway, this is probably a symptom of a specific way of Shareaza crashing and will get fixed automatically if the crash causing bug is fixed.

Maybe it tries and fails? Actually what I was thinking about was that maybe the serialization of the host cache fails causing both the crash and on restart the failure of the host cache to supply peers. So the crash and lack of connection would be the same bug with two different symptoms. That is what I meant with being automatically fixed.
