Description bugs.kde.org 2009-11-15 13:17:59 UTC

Version:           0.10.0 (using 4.2.2 (KDE 4.2.2), Kubuntu packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.28-16-generic

Howto reproduce the wrong behaviour:
1) Open EXIF comment edit form (Image > Metadate > Edit EXIF)
2) Edit comment
3) Click OK
4) Now the edited picture is only displayed partial

For digiKam to display the picture correct again:
1) Edit EXIF comment form (Image > Metadate > Edit EXIF) again
2) Do not edit anything
3) Click close
4) Image is reloaded and displayed correct now

I will add a screenshot.

Comment 2 Marcel Wiesweg 2009-12-07 17:20:28 UTC

Can you reproduce the problem regularly and with other pictures?
I would recommend to test with 1.0-rc1 (or 1.0, to be released in a few weeks).
What is your version of kipi-plugins, exiv2 and kexiv2? (Help -> Component Info)

Comment 3 bugs.kde.org 2009-12-08 02:28:38 UTC

I can reproduce this issue almost always.

But I am working with bigger pictures (at least 2 MB) on a Netbook.
Perhaps some kind of race condition.

According to synaptic:
kipi-plugins 0.2.0-1ubuntu3
exiv2 0.18-1ubuntu1
kexiv (not installed)

According to digiKam (version 0.10.0):
LibExiv2 0.5.0
LibKipi 0.3.0

Comment 4 caulier.gilles 2009-12-08 08:23:26 UTC

According to synaptic:
kipi-plugins 0.2.0-1ubuntu3
^^^ TOO OLD. We are in 0.9.0 !!!

exiv2 0.18-1ubuntu1
^^^ 0.18.2 is out. Recommended...

kexiv (not installed)
^^^ IMPOSSIBLE !

According to digiKam (version 0.10.0):
LibExiv2 0.5.0
^^^ this is better (:=)))

LibKipi 0.3.0
^^^ not important there

Comment 5 Marcel Wiesweg 2009-12-09 18:28:48 UTC

This really sounds like a race condition (not between threads, on system level) as if an image is read while written.
But the kipi plugins should call KipiInterface::refreshImages() when it's finished with an image, which will again reload the image.

Comment 6 bugs.kde.org 2009-12-13 14:59:55 UTC

I updated to DigiKam 1.0 beta 5 - respectively I upgraded ubuntu to 9.10.
The problem is fixed now. Thank you guys!
