I've been getting that same alert several times a day for months now, ever since the Sense 6 update. I haven't been able to find any info on what it is, or whether or not it can be shut down.
I used a program to delete the Zoe app (Since it is a system app, I couldn't do it from the App Manager
Since that, I'm getting an error message with this com.htc.zero any time when I go into the Gallery .
Probably it's connected with Zoe(?)
