GenerateApplicationManifest error

My team and I get this error often but random and we're not sure why it does this. To get around it we either build the solution a couple of times of have to restart Visual Studio (10). Here's the error i have when i try to build :

Error 5 The "GenerateApplicationManifest" task failed unexpectedly.
