According to the scanner attributes it should be similar to

GGGGGGGGBGBGBGBGBGBGBGBRGBRGBRGBRGBR....

where each letter represents one line of the respective color.

It is strange that the 0.7 version behaves different, because I
didn't change anything with regards to the data processing.

If you enable debugging with SANE_DEBUG_MICROTEK2=40 you
should see that a function segreg_proc_data() is called, that
processes the data.

I have a scanner that uses the same data format, so I can try it
myself first. If neccessary I will get back to you.
