I did and upgrade from (K)ubuntu 12.04 to 12.10. It all worked well -- except for Gimp.

Gimp 2.8 works fine but loading a .NEF file (a raw file from Nikon) fails with the message

Opening '/path/to/file/DSC_2605.NEF' failed:

Procedure 'file-ufraw-load' returned no return values

I have ufraw and gimp-ufraw installed.

How do I find out what is wrong and how do I fix this?

Removing gimp-ufraw and installing gimp-dcraw helps. However, dcraw is not as nice as ufraw because it doesn't have an interactive user interface.

Use the UFRAW to process a .NEF file first, then Gimp should recognize ufraw as the sub-application to import with.

To use the UFRaw Gimp plug-in you need first to install Gimp 2.0 or higher. Gimp 2.4 is recommended. If you only plan to use UFRaw's stand-alone tool, there is no need to install Gimp, but the Gimp Tool Kit (GTK+2) is still needed. There is no need to install DCRaw itself since its code is incorporated into UFRaw.

I know, that was a expose from the UFraw web site – Ringtail Nov 17 '12 at 23:22
