ipad/iphone deployment to device via monotouch

Question

I have built 2 apps: one for iPhone, one for iPad. They both build perfectly fine and run within the simulator. They also ran fine on the device prior to updating to Xcode 4.3.2.
When I build to the device with MonoTouch, I get this message:

Please ensure your device is connected...  
Connected to: Steve’s iPad  
Initializing file service...  
Uploading application  
Finalizing file service...   
Installing application  
Installation failed: AMDeviceInstallApplication returned: 0xe8008017  
The application was terminated by a signal: SIGHUP

When I look at the console via Xcode/Organizer I see the following messages:

Has anyone else had this issue, or is there anyone out there who is better equipped to decipher the above stack trace?

The crucial part is this:

Could not copy validate signature: -402620393

If you google this error, you will find a number of ideas:

Delete the app manually from the device first, then try to upload again.
Ensure that the provisioning profiles are configured correctly in Xcode. This usually means delete them all and download them again.

I can also throw in a couple ideas of my own:

Check if the same thing happens to a new project from a template. If that works, there is something in your app that's causing the signature validation to fail.
Check if the same thing happens to a new Xcode project (and if it works, try again with your project; Xcode is know to do some automatic configuration in some cases)
Reboot your device and Mac.
If you have another device, try there.
