No problem here using the last dcraw version. Witch dcraw release you use ?

Can you give me a CR2 sample file to test ?

Works here without problems. Thumbnail is there, image opens, histogram is there.
If you ignore in console output all warnings from libexiv2, the important lines when opening the image are:

digikam: /media/fotos/Digikam Sample/RAW/img_1673.cr2 : RAW file identified
digikam: Running dcraw command (dcraw,-c,-w,-a,-o,1,/media/fotos/Digikam Sample/RAW/img_1673.cr2)
digikam: Parsed PPM header: width 3522 height 2348 rgbmax 255

right.

If i understand you, you have installed showfoto using a bin package, not using source code tarball. Right ?

If yes, i suspect a bin package problem, and i recommend you to try to compile and install digiKam using source code to validate this way. Thanks in advance

I also have this problem.
I am running Ubuntu Dapper 6.06 up to date.
I installed 0.8.2-rc1 from Ubuntu repository, worked perfectly, but very slow to display the cr2 files.
I uninstalled, and get binary .debs from http://kubuntu.omat.nl/dapper/
These exhibited the same problem as above, so I downloaded the source and comiled locally.
Compiled from source I still get the same behaviour.

This is the problem :

> digikam: Dcraw StdErr: Unknown option "-2".

The -2 option from dcraw have been deleted !!! This dcraw option uncompatibilty is a shame !

This problem have been fixed into next 0.9.0-beta2. The tarball are available for testing at this place :

http://digikam3rdparty.free.fr/0.9.0-beta2/

Please give us a report. Thanks in advance
