I think I may have found out what the trigger for the crash is. It is libkcdraw
related but in how it (or digikam) handles unusual .dng files. 

Namely 16bit BW .dngs. I was surprised by that type of file is possible but
Vuescan allows you to do that. 

With the offending files included the console showed this just before the crash

/media/data/images/scanned/Nikon/Scan-100810-0001.dng: Cannot use camera white
balance.
Scaling with darkness 0, saturation 65535, and
multipliers 1.000000 28226.382812 28226.382812 28226.382812

KCrash: Application 'digikam' crashing...
sock_file=/home/jon/.kde4/socket-funtoo-pc/kdeinit4__0


Without that file and another 2 the crash stops. I still have those files if
you want them (they're bit big) for testing.
