git stable branch
Darktable segfaulted when I tried to open a specific month's (2008:06) folder.
This happened on 2.6.0 on Debian.
I then installed 2.6.2 and the same happened.
Only on this folder. So I duplicated the folder, removed the xmp´s of the duplicated folder, imported that in to Darktable and it worked without a problem. I then rsynced it back to the original folder, removed the backed up folder in Darktable and the problem stopped.
So something in an xmp must have caused this. I attach a trace file.
