Software darktable
1

When I start Darktable ( linux mint19 and darktable 2.4.4) it will open for a while and then turn off itself.

error message:

to@arto-HP-ENVY-15-Notebook-PC:~$ darktable
[tiff_open] warning: TIFFReadDirectory: Unknown field with tag 18246 (0x4746) encountered
[tiff_open] warning: TIFFReadDirectory: Unknown field with tag 18249 (0x4749) encountered
[tiff_open] warning: TIFFReadDirectory: Unknown field with tag 36867 (0x9003) encountered
free(): invalid pointer
Keskeytetty (luotiin core-tiedosto),

Can anybody know how to remove this error?

Edit: Problem solved. One file was corrupt. Fortunately, the pictures were still on the memory card, I opened them again.

Maybe this error message is enough for the real experts, but in the meantime I suggest to start darktable with darktable -d all to get more information.
