RAW pixel size in app is more than in camera. Fuzzy edges on editable / exported images.
Using darktable 1.0.5 on Ubuntu 11.10 for Sony Alpha SLT-A65 raws. After export image from darktble there is small fuzzy edges on full-sized images. Camera produces 24mp 6000x4000px JPEGs with normal edges. Full-sized image exported with darktable have 6048х4024px and fuzzy edges.

I confirm your findings. There is a right border with some garbled pixels when processing your raw file.
ufraw suffers from the same problem (also producing a 6048 x 4024 output).
dcraw does not show this problem (producing a 6024 x 4024 output).

Adding the following seems to fix the issue:
<Camera make="SONY" model="SLT-A65">

<Color x="0" y="0">RED</Color>
<Color x="1" y="0">GREEN</Color>
<Color x="0" y="1">GREEN</Color>
<Color x="1" y="1">BLUE</Color>
<Crop x="0" y="0" width="0" height="0"/>
<Sensor black="520" white="16596"/>

Ok, so that got mangled (don't use the above).
I've just committed a proposed fix to master:
I still have to talk to Klaus Post about this, if this is the correct approach, but it should get you by at least.

So that wasn't a proper fix after all...
Thanks to Klaus Post there is a proper fix now:
