http://bugs.kde.org/show_bug.cgi?id=167139         
           Summary: crash if Exif.GPSInfo.GPSAltitude is empty
           Product: digikam
           Version: unspecified
          Platform: Mandriva RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: shadow.walker free fr


Version:           digikam-0.10.0-0.824037.2mdv2009.0 (using KDE 3.5.9)
Installed from:    Mandriva RPMs
OS:                Linux

When launching digikam, it scan my pictures folder and crash when reading picture with an empty Exif.GPSInfo.GPSAltitude value. If I open the file with showfoto, showfoto crash only when I open de marble(geolocation) tab.

If i try to get exif data with exiv2(0.17.1) I get:
- this picture is loaded fine:

Can you file a gdb bactrace to see where the crash appears in source code.

Thanks in advance

The crash appear in Exiv2.

Andreas, i think Exiv2 mess an exception rule in this case. right ? Of course, something can be done in libkexiv2.

In getGPSLatitudeNumber we check for count() of the Exifdatum. The docs of toRational(int n) says the behavior is undefined if there is no n-th component.
Question is if in this case count() is 0, if this is a valid situation with the Exiv2 API (maybe with broken files, but thats not the point), and if we should always check for count()

In Exiv2 a value with 0 components is considered valid. So yes, Marcel is right, digiKam needs to check count() to make sure the required component exists in the value before accessing it in that way.

I thinks there are more issues in the interaction of exiv2 0.17.1 and digikam:
When i scan my library digikam crashes on almost all non-Canon or non-Nikon files plus hugin panoramas. Most errors are "invalid type 0".

This is a hugin example:
Error: Directory Image, entry 0x0000 has an invalid type 768; skipping entry.

showfoto kde3 and kde4 crash the same way, so I guess it's really an exiv2 issue or the interaction between digikam and exiv2

Gerard,

Judging from the backtrace, the crash is from the SVN version of Exiv2, not from version 0.17.1. If everything was cleanly compiled with the SVN version then that's good, it needs this kind of testing. But please make sure you don't have a mix of Exiv2 versions, there have been cases where digikam loaded one version of exiv2 and libkexiv2 depended on another one.

If you think it's an exiv2 issue, can you please send me one of these images to ahuggel at gmx dot net?

Thanks
Andreas

PS: I'd say this is a different issue from that of the OP.

Test image has been sent.

I tested the crash with 0.9.4 (which uses the same libkexiv2): same crash when I ask the metadata to be re-read into the database. For me this points to exiv2 or the way libkexiv2 is handling exiv2 errors.

I cleaned my machines from everything *exiv2 and *kexiv2, recompiled 0.17.91 from svn and the pb remains the same.
$ ldd /usr/lib/kde4/bin/digikam|grep exiv

Now I went back to exiv2 0.17.1 and all works without a flaw.

Gerard, thanks for the image.

You were right, this is an Exiv2 issue, I can reproduce it with the SVN version of Exiv2 aka 0.17.91:

ahuggel mowgli> ./exiv2 -M'set Exif.Image.Software GI' Chambord.jpg

Gerhard,

This should be fixed. Please retry with Exiv2 from trunk, rev 1551 or later and confirm if it works.

Thanks,
Andreas

Hi Andreas,

I tried it on 443 images that caused a crash before from different cameras: no problems anymore (:-)))))
