master experimental was fixed by removing the old broken pkg from the repo.
If we know the root cause of the error, we can test the fix on the 4.1 job now.
from where id you remove it? It made it into 'tested' so, you probably also needed to remove it from the local cache on the slave.
The root cause was the bad SDK package.
But it also uncovered the truth that daniel's new patch was not really working and not taking the SDK from experimental. This made the fixed SDK not come into play.
