Same happened to me after latest update only.
I run two self hosted wordpress blogs off the same server.
The one with this plugin died, The other is fine.
I disabled all plugins apart from this one, and still dead ( i killed it with ftp in the end )
However, all i really had was Jetpack, twitter digest & mapmyrun embedder.
Even with those off, and this only on, it was unuseable in dashboard and front end.
WordPress 3.3.1
Apache version 2.2.17
PHP version 5.2.14
MySQL version 5.0.95-community
