Auto-applying of GPX tracks is unreliable
When I import a directory with images and GPX files, Darktable tries to geotag the images according to the GPX files. However, I have to re-import at least once to have all GPX files applied. I think it has something to do with the fact that some of the GPX files don't share timestamps with the images, i.e. no image can be geotagged using them.
This is difficult to reproduce (race condition?). I prepared a sample directory which exhibits this bug on my system, but it is 144 MByte in size, and it contains somewhat privte images. I give the link to anyone interested in investigating this further, of course.
