Cropping video with height=1 fails

Description

Summary of the bug:
Cropping a video with height 1px fails:
"-filter crop=848:1:0:240" fails with error message:
"[Parsed_crop_0 @ 026cff60] Invalid too big or non positive size for width '848' or height '0'"
How to reproduce:
Use a video as input an crop to a 1px high strip.

I know this is not very helpful but this instruction was working well with a ffmpeg version from September 2012. I am afraid I can not provide the version I used back then.

A height of 2px works fine.
I used a this

ffmpeg -i c:\strip\GOPR0492.MP4 -filter crop=848:1:0:240 "out0%6d.png"
