Description Paweł Marciniak 2008-07-03 08:29:19 UTC

Version:           0.9.3 (using KDE 3.5.9)
Installed from:    Unlisted Binary Package

When a negative altitude is assigned to a photo in the correlation process, that photo's exif data becomes corrupted and causes digikam to crash when displaying it. The workaround is to search for photos with negative altitude before clicking 'apply' in the correlator window, and manually change the altitude to some positive value.

I'm filing this as digikam bug because I'm not sure whether it's the plugin's fault when writing metadata or digikam's when displaying it.

Changed severity to "crash". I hope to have selected only the right bugs (>100) :-)

Comment 2 caulier.gilles 2008-11-19 20:34:24 UTC

But, thi sbug have been fixed in the pass if i remember. Please try with current Exiv2 library (next 0.18) and curent libkexiv2 library (next 0.1.7) using code from subversion repositories...

Pawel,

This file still valid using kipi-plugins 0.1.6 and a recent version of Exiv2 library ?

Comment 4 Paweł Marciniak 2009-01-21 04:37:05 UTC

Gilles,

Unfortunately, I don't have that photo anymore, so I'm unable to verify. :(

Comment 5 Andi Clemens 2009-09-13 14:35:14 UTC

Should we close this one then?

Comment 6 Michael G. Hansen 2009-11-26 12:21:48 UTC

Negative altitudes work fine here with libexiv2 0.18.2, libkexiv2 0.6.0, kipi-plugins 0.8+svn, digikam 1.0beta6+svn

Comment 7 caulier.gilles 2009-12-25 20:24:20 UTC

Kipi-plugins 1.0.0 is out since few days...

http://www.digikam.org/drupal/node/492

Please try with this version.

Thanks in advance
