Description Mark Harrison 2010-10-26 07:16:36 UTC
Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

Kphotoalbum version 4.1.1 running in Ubuntu 10.10

I've found a number of photos of mine that cause KPA to crash immediately after startup when it attempts to load them.  Running the 'exif' command line tool on these photos indicates that there may be corrupt exif data.  Other programs like gthumb seem to have no problem displaying or reading the exif data in this photo.

I've attached one of the problem photos.

I'm not sure if this is related to bug 237889 (https://bugs.kde.org/show_bug.cgi?id=237889).

Reproducible: Always

Steps to Reproduce:
To reproduce with demo database:

1. Run kphotoalbum -demo
2. Quit without deleting demo database
3. Copy photo attached to this report into demo database (/tmp/kphotoalbum-demo-$USER/)
4. Run kphotoalbum -demo again

Actual Results:  
KPA crashes immediately after startup.

Photo that crashes KPA.  Possible corrupt EXIF data.
Comment 2 Mark Harrison 2010-11-08 12:27:10 UTC
Created attachment 53241 [details]
Output of "exif -d" on attached photo to show which data is corrupt.
Comment 3 Mark Harrison 2010-11-11 03:49:14 UTC
Stripping all metadata using "jhead -purejpg" allows photo to be imported without crashing.  Obviously, this isn't an ideal solution.
Comment 4 caulier.gilles 2010-12-13 08:49:30 UTC
This crash is relevant of exiv2. I CC Andreas for info.

Comment 5 Mark Harrison 2010-12-17 16:38:14 UTC
I managed to work around this bug by using exiftool to fix the exif tags, specifically:

exiftool -XResolution=180 -Orientation='Horizontal (normal)' $pic

These two tags (XResolution and Orientation) were invalid (or blank) from all the photos that caused KPA to crash.

exiftool -Orientation $pic
Orientation                     : Unknown ()

exiftool -XResolution $pic
X Resolution                    : 

Actually, only the Orientation tag needed to be fixed in order for it to be properly loaded into KPA. So, 

exiftool -Orientation='Horizontal (normal)' $pic

was sufficient.
Comment 6 Miika Turkia 2010-12-22 06:40:51 UTC
This should be fixed now in revision 1208526.
Comment 7 Andreas Huggel 2012-01-17 00:55:56 UTC
Which version of libexiv2 are you using?
Can you post the output of exiv2 $pic and exiv2 -u -pa $pic from one of the problematic images, or does that crash too?
Comment 8 Andreas Huggel 2012-01-17 00:57:01 UTC
Forget my post above. Didn't realize this was that old.
