That's because you have to do all the image manipulation to get from
a negative scan to an acceptable positive yourself. You can use a frontend
that does this step for you or at least makes it easier (e.g. XSane or
IScan!), but it is possible to do it manually and get good results.
I have a short step by step instruction on my web site 
(http://khk.net/sane/gimp_negative_scanning.html).

This is very likely a timeout condition that is caused by an older
kernel. Which kernel version are you using?
