Description Tom Vincent 2015-06-17 09:52:06 UTC
GPhoto correctly finds my device over MTP. However, when I press "import" from the device, digiKam segfaults.

Reproducible: Always

Which OSX did you use ?

Do you have video files on your camera ?

Gilles Caulier
Comment 2 Tom Vincent 2015-06-17 10:34:10 UTC
OS X Yosemite 10.10.3. Yes, there are videos on the device.
Comment 3 caulier.gilles 2015-06-17 11:27:16 UTC
Ok.

To test, can you import files from camera without to have video files (typically images only as JPEG and RAW).

For video files, there are bugs in Exiv2 0.24 library which crash digiKam. We have a lots of reports about.

Exiv2 0.25 is not yet released. This version will fix these problems.

Tom, 

I build digiKam 4.11.0 PKG installer for Yosemite, including new Exiv2 0.25 :

http://download.kde.org/stable/digikam/digikam-4.11.0-Yosemite.pkg.mirrorlist

Please test and give us feedback.

We have also a patch for another problem relevant of ImportTool view init, but it will be included to next 4.12.0 release.
