I've noticed a strange crash. I've an image taken with a Casio Exilim EX-Z150. When I try to rotate it digikam crashes. This is the console log: *** digikam.general: Detected change, triggering rescan of "/home/miquel/sanas/fotos/2013/per ordenar/2013-08-14-estrena càmera nikon d5100/" digikam.database: Starting scan! digikam.general: Detected change, triggering rescan of "/home/miquel/sanas/fotos/2013/per ordenar/2013-08-14-estrena càmera nikon d5100/" digikam.general: LoadingCache slotFileDirty "/home/miquel/sanas/fotos/2013/per ordenar/2013-08-14-estrena càmera nikon d5100/2013-08-14 19-41-41.JPG" digikam.general: Detected change, triggering rescan of "/home/miquel/sanas/fotos/2013/per ordenar/2013-08-14-estrena càmera nikon d5100/" digikam.metaengine: Metadata for file "2013-08-14 19-41-41.JPG" written to file. digikam.general: Detected change, triggering rescan of "/home/miquel/sanas/fotos/2013/per ordenar/2013-08-14-estrena càmera nikon d5100/" digikam.metaengine: Orientation => Exif.Image.Orientation => 1 digikam.dimg: "/home/miquel/sanas/fotos/2013/per ordenar/2013-08-14-estrena càmera nikon d5100/2013-08-14 19-41-41.JPG" : JPEG file identified digikam.metaengine: Loading image history "" digikam.metaengine: DateTime => Exif.Photo.DateTimeOriginal => QDateTime(2013-08-14 19:41:41.000 CEST Qt::TimeSpec(LocalTime)) digikam.database: Starting scan! digikam.metaengine: Exif color-space tag is sRGB.

Excuse the formatting, I haven't found an option to format console output!
In gdb, when I enter the image it hangs.

Yes, it's an Exiv2 library crash. Report this problem to Exiv2 bugzilla with relevant image to test. Gilles Caulier
Thanks Gilles, but the buf is solved in exiv2, I posted in the middle of the first comment: *** But googling around Ive found this bug (Crash in exiv2 due to assertion when setting rating on jpg with a Casio makernote): http://dev.exiv2.org/issues/1106 I'm using Ubuntu Gnome 16.04 with the packages provided by Philip Johnsson, and I had not installed exiv2.

No. digiKam do not have a copy of Exiv2 library. It's a run-time binary compatibility between Exiv2 .so and libdigikam.so Gilles Caulier
