hm. the way i would go at it is try to revert any of those

$ git log --oneline -- src/common/exif.cc
26bdf59 Don't crash when GPSLatitudeRef is missing
0acb6bf exif.cc: Support Minolta 5D special rotation too
438fca4 exif: one more crash fixed hopefully.
e9ad7f9 exif reading: fix a couple more array out of bounds things.
87ea1c3 fixed segfault when loading half-corrupted xmp
88cbc20 dng: don't delete meaningful exif in case of dng.
79feaae Be a bit more regression safe: handle standard ISO tags the
same as before (however not sure if that was really correct?), and
non-standard ones in the way exi
a3c5d48 Read ISO from EXIF differently (similar to inside exiv2's
"fixiso" setting), and hope this will be the correct way now (works
for d5100 at least, please check
b75046a Merge pull request #135 from jcsogo/exif
b3e2862 Guard old version of Exiv2 against the Samsung2 MakerNote cleanup
8983e75 Set properly Subject Distance for Nikon cameras. Fixes #8541
3f98225 multi-instances: fix a possible null dereference in xmp writing
7083cb4 Store stuff in ordered arrays in XMP files
c0dade0 dt_exif_read_blob: minor refactoring
b522516 multi instances: fix a crash when importing an xmp.

and see if it starts working again (i'm at work so can't do that for you now..)
