Accounts are not showing in Mist0.8.5

System information

Version: `0.8.5`
OS & Version: linux
Node type: `geth(default)`

Accounts are not showing up in Mist 0.8.5.But I can see my accounts in keystore folder of .ethereum directory. I even added a new account to Mist, but that too did't show up but one more file was added in keystore representing newly created account. Even on checking developer's tool of Mist, I can see all my accounts when I enter web3.eth.accounts. So why accounts are not showing up in wallet?
