After updating to version 2.2 (46), Sourcetree is constantly popping up an alert asking if it can use the git credentials from my keychain for github.com. Nothing happens when I press both the "Always Allow" button and the "Allow" button, but the "Deny" button still works. After I press "Deny", the popup comes up again and I press "Deny" again and it leaves for good. Then the action I was trying to do (fetching for example) completes successfully.

Other details:

• Terminal still works without asking to use my credentials
• My repos from bitbucket.com are still working
• Github.com is not having problems as far as I can tell
• I already tried restarting my computer
• This popup comes up even when I don't perform an action (probably from the automatic background repo check?)

Update: I fixed this myself by deleting the keys for "github.com" from the keychain.
