3 years ago I also occasionally get "random" failures on QR codes, even synthetic B&W, well-resolved ones. I feel (not much evidence) that its related to vertical black lines.
If you crop the black box around you code (but otherwise identical image) does it work?

Hi
I have been testing out pyzbar and it seems to be working 99.9% but every so often it misses a decode and i am not sure why.
For example no matter what I do pyzbar misses 44788 in the attached file. If I print the file a handleld scanner has no problem decoding 44788.
TIA Glenn
