Android Gallery force closes when Share pressed, or "I'll make him a (sharing) offer he can't refuse!"

Recently, I ran into a problem on my Samsung Galaxy S3 phone's Gallery app. When I pressed the Share button, the Gallery would force close with an error "the Gallery app has closed unexpectedly."

I knew it was something recent that broke the Gallery, as it was working a couple of weeks ago. After some quick internet research, I came across a solution that fixed the issue.

Make sure the "Picture Artist" built-in app is not disabled/turned off.

Apparently something in the built-in Paper Artist app is used when Share is pressed in the Gallery. I had turned off Paper Artist last week (along with every other bloatware app I could find). As soon as I turned Paper Artist back on, I was able Share again.

Now I know, and knowing is half the battle.
