Description greatbunzinni 2007-10-26 20:53:59 UTC

Version:           0.9.2 (using KDE KDE 3.5.7)
Installed from:    Ubuntu Packages

Digikam crashes when the user tries to save a image which is being showned by digikam's image viewer and that was loaded directly from the camera. The crash can be reproduce by following these steps:

- connect a camera which has photos stored in it's memory
- launch digikam
- read the camera's content (in my case, "camera"->"USB PTP class camera")
- open an image file by clicking on a thumbnail
- on the digikam's image viewer, save the file as "file"->"save as".
- digikam crashes in a fiery ball of evil flames of fail.


Here is the crash backtrace:

SVN commit 733624 by cgilles:

There is no ImageInfo instance available to store digiKam properties in image metadata.
