Blank alt attributes for images - best practise?

for

What is the latest recommended practise for markup of blank alt
attributes for images? I've had conflicting advice of two sorts:

1. Use a space between the quotation marks (alt=" ") to prevent older
screenreaders reading out the file name

2. Don't use a space between the quotation marks (alt="") as it causes
other problems

What are your thoughts/experiences? Can anyone provide a list/partial
list of user agents that misbehave (along with the nature of the
misbehaviour) in either scenario 1 or 2?

Cheers,
Dey
