Filter an array by content

Found the problem. My script local was being emptied for some reason, so 
there was nothing to filter. After repopulating all data it worked.

My only excuse is that I've been avoiding stepping through the debugger 
because LC has been crashing when I do that. I've sent in many crash 
logs but it's only recently I've discovered it happens only with Step 
Over. It's hard to believe no one else has seen this, which I've been 
seeing since LC 9 first came out, but that's why I didn't know what was 
in the variable. Now that I've discovered breakpoints don't crash as 
long as I don't step through, I was able to see what's going on.

If you have experienced crashes during debugging, take a look at 
https://quality.livecode.com/show_bug.cgi?id=22130 and 
https://quality.livecode.com/show_bug.cgi?id=21876

I have several more in my collection that I haven't uploaded yet.
