I’ve recently loaded Gimp and the Ufraw plugin into 16.04 so I can process canon CR2 raw files. Trying to open CR2 files via Gimp/File/Open, or if I select the same file via UFRaw I get the error: “Opening 'file location & name' failed: Procedure 'file-ufraw-load' returned no return values”.

Gimp loading and working with JPEGS works OK.

Note if I start Gimp via the terminal there is a page of warnings same as in 831794; eg

(gimp:5187): GEGL-gegl-operation.c-WARNING : Cannot change name of operation class 0x14F74B0 from "gimp:point-layer-mode" to "gimp:dissolve-mode" etc

Running UFRaw from the terminal also generates the 1st error above as well as Segmentation fault (core dumped) in the terminal. If I run 'strace ufraw' it results in the following when UFRaw crashed: which gave the following when it crashed:

open("/home/daniel/.local/share/lensfun", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = -1 ENOENT (No such file or directory) --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x4} --- +++ killed by SIGSEGV (core dumped) +++ Segmentation fault (core dumped)

I haven't been able to find anything like this searching the web. Can anyone shed light on this issue? If anyone can help me to get UFRaw running properly I would appreciate it.

This is a known issue.

There is a Confirmed bug report on launchpad here

There is also an upstream bug report on bugzilla for Gnome here

The general consensus is that they are going to move to gegl 0.3

This has not been implemented yet. The last update was 2016-09-10 22:20:37 UTC

    It would be nice if Debian & Ubuntu could finish their unilateral dependency change and also perform the required changes to GIMP itself, though :) Dec 5, 2016 at 13:47

    Thanks for the info. At least I now know it's not something I've messed up on my PC. :)
