Since some time I cannot open raw files from GIMP. darktable is correctly selected as raw plugin from the preference window but - when I try to open a .NEF file - darktable starts but its window remains black and hangs.
When dt window is killed GIMP says the Nikon import plugin failed. I also launched GIMP from a terminal but cannot see any useful message...

Thanks, Maurizio

Yes, sure! It works well as usual.

Does starting darktable directly, i.e., stand alone, work?

Hi Tobias,
please apologize for my poor accuracy... you are right. GIMP 2.10.10
darktable 2.6.2
OS Linux
Open SuSe Leap 15
X11 graphics

I upgraded GIMP yesterday from 2.10.4 to 2.10.10 and changed also the repository furnisher (from 'graphics' to 'opensuseitalia') but the problem was there also with GIMP 2.10.4 from 'graphics' repository.

Thanks!! Maurizio

Hi,

then the usual questions: Gimp version?
Darktable version?
Operating System and Version?
If Linux X11 or Wayland?
Any thing else, that could help.

Regards, Tobias

Well, then please try running GIMP like this:

DARKTABLE_DEBUG=green_is_my_pepper gimp

That should show some more debug prints.

Do you maybe have a version of dt that was compiled for another version of GTK
than what you have installed? Maybe something that was intended for another release of your distro?

That being said, could you try to run the same command as lined out in the top
of the mail? With all the --conf arguments, ...? Maybe add a "-d lua" to it,
too.

Almost. This should (more or less) work:

1. Start GIMP and open a raw file in there.

2. Wait for darktable to hang.

3. find the PID of darktable using "pidof" (or "ps").

4. run "gdb darktable 12345" with the PID instead of 12345.

5. Hit ctrl-c, you'll get a "(gdb) " prompt.

6. Enter this:

set pagination off set logging file gdb.txt
set logging on
thread apply all bt full
quit
y

7. Send me the file "gdb.txt" that was created.

Hi!
More information.
My ~/.config/darktable/luarc is very articulated because it has been modified in order to use the Script Manager by Bill Ferguson. If I rename luarc in luarc.orig (so dt will ignore it on load) then GIMP opens dt and dt will load the NEF file correctly! When I exit GIMP the EXR file is created but GIMP will crash with the following errors:

Hi,
finally all works now!
Start GIMP
File -> Open (select a raw file)
darktable is launched and the raw file opened Close dt
GIMP loads the file.

I renamed my ~/.config/darktable/luarc in ~/.config/darktable/luarc.orig so dt do not load it at startup.
This is the ONLY way I fund in order to solve the problem. Not loading the luarc file means I cannot use some lua utilities in dt like enfuse, pano, etc.

Maurizio
