I'm not sure, but I managed to fix the problem about 10 minutes ago by
installing the dependencies required for compiling DT from git. I assumed
that the AUR manager would pull everything in, but I think it didn't and
that might have been the main issue.
I also initially thought it might have been a corrupted XMP file but I
tested that by copying one photo elsewhere without the XMP and importing it
back (after deleting the library.db file), and it still crashed with the
same error.
I don't know how a couple of missing dependencies would produce a ptrace
error but I'm just glad I managed to fix the problem.
