Cannot edit RAW files in GIMP under Lubuntu 18.04

[steve davis]

Since Lubuntu 18.04 I've had problems editing RAW files (.pef) with GIMP.

When opening a RAW file, gimp-ufraw displays/edits the image OK. But but when I press "OK" I get a GIMP error message:-

 Opening '/home/steve/Pictures/RAW/DAWN1384.pef' failed:

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

This worked fine on earlier versions of Lubuntu.

Current versions:-

GIMP: v2.8.22-1

gimp-ufraw: 0.22-3

uname -a output: 4.15.0-33-generic #36-Ubuntu SMP Wed Aug 15 16:00:05 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Additional insformation.

If I run ufraw from command line and then use the ufraw GUI button for Gimp, I get this output in the terminal:-

For 'buntu 18.04
liblensfun1 0.3.2-4 located in: /usr/lib/x86_64-linux-gnu

pre-18.04: liblensfun0 0.2.8-3

I suspect lensfun files may be in wrong location on 18.04, so I tried copying liblensfun.so.0.3.2 to /usr/local/lib/x86_64-linux-gnu/ (then ran: sudo ldconfig)
This did not fix.

This bug is probably related to:-

Thanks to @launch-faygate's analysis in this bug, I came to a workaround on Ubuntu 18.04, and nufraw.

First, note that `nufraw` has also this option:

  nufraw --out-type=jpg --lensfun=none mypic.DNG

... however, it still causes the same "Procedure 'file-nufraw-load' returned no return values".

So I decided to try the old version of liblensfun0 (0.2.8), which luckily is still online:

---
wget http://mirrors.kernel.org/ubuntu/pool/universe/l/lensfun/liblensfun0_0.2.8-1_amd64.deb
dpkg --contents liblensfun0_0.2.8-1_amd64.deb
mkdir liblensfun0_0.2.8-1
cd liblensfun0_0.2.8-1
dpkg -x ../liblensfun0_0.2.8-1_amd64.deb .
readlink -f usr/lib/liblensfun.so.0.2.8
---

Once you get the absolute path to liblensfun.so.0.2.8, note that used like this:

---
LD_PRELOAD=/path/to/liblensfun0_0.2.8-1/usr/lib/liblensfun.so.0.2.8 nufraw --out-type=jpg --lensfun=none mypic.DNG
---

... when you click the Gimp button, Gimp will open, there will be no report of error - but no image imported inside Gimp either!

However, this works:

---
LD_PRELOAD=/path/to/liblensfun0_0.2.8-1/usr/lib/liblensfun.so.0.2.8 gimp mypic.DNG
---

This will auto-open `nufraw` for importing the .DNG image, and once you click the "check" button, the image will finally be imported into Gimp.
