Failing cryptocomposertest

[Sandro Knauß]

Hey,

cryptocomposertest are failing for a long time. I started to debug it and it 
seems the problem is that d->content is not more accessible in the lambda 
function[0]. d->content is coming from MaintextJob. I also tried to replace 
the lambda function with a proper one, but nothing has changed. 

If I replace the async part with a sync part [1], than the tests run 
successfully.

When I switched to async mode in April [2], those tests were successful. I 
haven't found any change inside messagecomposer that can explain why the tests 
start failing. So maybe something within JobBase/KJob/QGpgme has changed?
Can someone have a look and and help me to debug this?
