Comment 1 caulier.gilles 2017-06-22 21:42:38 UTC

digiKam 5.6.0 is now released and available as bundle for Linux, MacOS and Windows.

https://www.digikam.org/news/2017-06-21-5.6.0-release-announcement/

Can you check if problem still exists with this version ?

Thanks in advance

Comment 2 caulier.gilles 2017-07-23 18:27:55 UTC

New digiKam 5.7.0 are built with current implementation as pre-release bundles:

https://drive.google.com/drive/folders/0BzeiVr-byqt5Y0tIRWVWelRJenM

Problem still reproducible ?

Comment 3 j.alders1946 2017-08-18 13:39:11 UTC

Using PCLinuxOS KDE5 Plasma and showfoto version 5.6.0.
After resizing or cropping a picture and trying to save the modified picture,
Showfoto crashes. Version 5.5.0 does not have this problem.
Sorry, cannot produce a bugreport because PCLinuxOS does not have debug packages
available. Not all picture show this problem but pictures made with 
Casio-Exelim-10x.

Comment 4 j.alders1946 2017-08-23 15:50:08 UTC

Did somebody NOTICED my comment 3 ?

Comment 5 caulier.gilles 2017-08-23 17:22:28 UTC

Do you read comment #2 and #3. We want a feedback with the AppImage Linux bundle that we provide, not with the Linux distro package. We suspect a broken binary compatibility with packages.

Gilles Caulier

Comment 6 caulier.gilles 2017-08-23 17:32:34 UTC

Note : to run showfoto with digiKam appimage, use right arugment on command line :

[gilles@localhost Téléchargements]$ ./digikam-5.7.0-01-x86-64.appimage help
-- digiKam AppImage Bundle
-- Use 'help' as CLI argument to know all available options
digiKam AppImage bundle CLI options:
 without option     : run digiKam.
 <showfoto>         : run Showfoto instead digiKam.
 <debug>            : run digiKam into GDB.
 <debug> <showfoto> : run Showfoto into GDB.
 <help>             : show this help.

Comment 8 j.alders1946 2017-08-23 18:25:06 UTC

Allright, I overlooked comment 2 but can't I simply upload a "problem" picture
taken with my camera?

Comment 9 caulier.gilles 2017-11-30 09:31:01 UTC

Please update this entry from bugzilla with current 5.8.0 pre-release bundle to see if problem remain.

Comment 10 caulier.gilles 2018-03-05 12:16:46 UTC

We need a fresh feddback here using last digiKam AppImage bundle...

Comment 11 j.alders1946 2018-03-05 14:08:01 UTC

Dear Gilles,

I am now using version 5.8.0 and do not face any problems with this version!
So I think I can conclude that this bug has been solved.
Thanks for your effort.

Comment 12 caulier.gilles 2018-03-05 14:58:41 UTC
