To expand a bit further on the above mentioned resolution problem:

The RAW images are around 10 mb which seems correct but in the gimp they take 2.9 mb memory which is odd. It almost seems as if the data is there but the file index is wrong (don't know the RAW format but I hope you can understand what I mean )

Opening in UFRaw gives an error about not being able to use the camera white balance after which it hangs...

Also got some error about a TIFF directory something but can not reproduce it atm.

Lastly I'm still curious about other peoples resolution in the RAW images to know whether its just me or a general bug and will try with Photoshop later to see if that changes anything.
