I've noticed such behavior after installing extended contacts search plugin and going to check the plugin's about section. Similar errors were popping up even when I didn't try to open the contacts app itself. I think I was using recent contacts tab as well.
The issue was gone after I removed the plugin, didn't have courage to install it again. Still, it's a fantastic plugin, so will give it another try after PR1.3 upgrade.
Might be useful to someone who visits this thread in future.
