I think this is happening because Bibble (at least the version you're using) isn't applying the metadata in the LX5's RW2 file that tells it how to correct for the lens' deformations. Perhaps this is a setting in Bibble, or a missing feature in their RW2 converter. I'll bet if you convert your RW2's to DNG with Adobe's free DNG converter, Bibble be able to read and apply that data and produce a 'corrected' image. 

I've come to this conclusion (and found your question) by noticing the same artifacts you mentioned when using Picasa 3.8 to view images created using Adobe DNG Converter 6.4.0.139 from my LX5's RAW files. This happens when I ask Adobe DNG Converter to create files for "Camera Raw 5.4 and later", the max setting. This theory was backed up by the fact that the JPG preview looks corrected when compared to the image rendered by Picasa when it renders the DNG. Not only that, but the JPG preview rendered by Adobe DNG converter matches the JPG's that came straight from the camera for the same shot (clearly the converter is applying the same transformations that the camera did internally to make the JPG).

After playing around a bit, I discovered that the artifacts go away in Picasa 3.8 when I have the DNG Converter create files for "Camera Raw 4.6 and later". I assume this means Picasa 3.8 doesn't understand Camera Raw 5.4, but it CAN understand Camera Raw 4.6, and will apply the correction automatically to conforming DNG files. No more corner vignette and barrel distortion on the resulting DNG files in Picasa, and in theory all the information from the RW2 is in the DNG!

Also - I wouldn't be put off by the correction - it's a good thing - and supposedly no information is thrown away. The DNG / RW2 files contain the raw sensor data plus additional information on the lens / camera aberrations, and viewing software can elect to apply these transformations or not. The 'true' sensor data can always be accessed.

Why is the pixel count of RAW images from the Panasonic LX5 slightly larger than the generated JPEGs?
Using PowerShell on a SharePoint 2010 site, how can you create a new list from a list template found in the list template gallery?. I want to be able to add several lists at once (just in numerically ascending order). What I have is:

$web = "http://site"
Get-SPWeb $web | ForEach { foreach ($hotdesk in 1,2,3) { $_.Lists.Add("Hot Desk " + $hotdesk, "",
$_.ListTemplates["My List Template"])}}


However, 'My List Template' doesn't work, since it looks like it only uses the built in list templates, not any custom ones that have been created from an existing list or uploaded to the site.
