FIXED, APPARENTLY k3b incorrectly identifies scsi r/w drive as read-only

[Oliver Iberien]

I corresponded with Sebastian Trueg, the developer, who had a look, then let 
me know that the problem had been identified and that he's fixed it. The 
latest version of k3b (0.12.15) uses "SG IO for scsi commands with newer 
linux kernels. This should fix problems with scsi device detection." I'll 
have to wait for the port to see if it works in my case.

This is part of the beauty of open source stuff. I've sent him some Lucky Luke 
off his Amazon wishlist in gratitude.
