Silverlight Out-of-Box Launcher crash after Seesmic update

After launching Seesmic this morning, it recommended I update to the most recent version – Seesmic Desktop 2, version 1.1.0.1451, released on 1/13/2011.  After verifying that I have the correct version of Silverlight, 4.0.51204.0, I let Seesmic update itself.  When it was done, it said I would have to restart Seesmic to use the new version, so I exited the application.  Then this popped up:

Notice that the exception occurred in coreclr.dll.  A very brief online search indicates that this may not be specific to Silverlight; at least one case I saw was in .NET 3.x.
