Test .PNG image created in GIMP, with Exif.Photo.UserComment set to "????"
using ExifTool
SUMMARY
When digiKam attempts to retrieve metadata from an image using Exiv2, if the
Exif.Photo.UserComment field for that image contains an emoji (or any other
character outside UCS-2, I assume), digiKam crashes.
STEPS TO REPRODUCE
1. Select or refresh album folder containing an image with emoji in
Exif.Photo.UserComment (also occurs on startup when loading last-viewed album,
if that album has said image)
Alternatively:
1. Add UserComment to existing image using outside program (ex. Exiftool)
2. Select image in digiKam
OBSERVED RESULT
digiKam crashes.
Last DebugView trace reads:
00000367 48.04353714 [18128] digikam.metaengine: Exiv2 ( 2 ) :
iconv: Illegal byte sequence (errno = 42) inbytesleft = 4
EXPECTED RESULT
digiKam does not crash. Maybe ExifTool can be used as a fallback?
