The PubkeyListActivity lifecycle and the ServiceConnection lifecycle are independent. In the case that the onCreateContextMenu callback fires before the onServiceConnected callback, the bound field will be null in onCreateContextMenu (as well as in some of its callees and in the callbacks that it registers) and can throw an exception when dereferenced. This pull request fixes the issue by including a check that bound is non-null when computing the loaded boolean that guards the potentially failing dereferences of bound.
