Hi,
With me too, darktable always crashes when exporting images.
I cannot run a batch export of more then 4-5 images that it crashes, and sometimes even exporting 3 at the time I run into crashes. Rather annoying when you have to export large groups of files.
Besides, every time I have to reopen the program, check which was the last exported, set destinatinon folder again, and then finally export again. Time consuming.
Sad, it seems the issue is confined to a few users.
Best,
m
