           Summary: libexiv2 crashes on certain JPGs
           Product: digikam
           Version: 0.10.0-rc2
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: makuro at gmail.com


Version:           0.10.0-rc2 (using KDE 4.2.1)
Compiler:          gcc 3.1.2 x86_64 
OS:                Linux
Installed from:    Gentoo Packages

This bug seems similar to a few of the ones marked as resolved, but bear with
me. Basically, an exiv2 call when importing an image seems to crash digikam.
When running the exiv2 command line utility, it works without error. There's
nothing remarkable about the JPGs, except perhaps that it was taken with an
older digital camera.

Here is the backtrace. Like I said, it probably looks familiar:

Application: digiKam (digikam), signal SIGABRT

Running exiv2 (0.18) yields:

===========================

Perhaps most importantly, here is a file with which you can reproduce the
error.

1) Download http://makuro.org/~makuro/unl0805_1.jpg
2) Drag and drop it into an album/folder monitored by digikam.
3) If your digikam is like mine, it will close almost immediately with a
SIGABRT
4) removing or chmod 000ing the file will allow your digikam to open again.


As far as I can tell, I'm running the latest releases of all software involved.
Please let me know if there's any additional info I can provide.

Thanks,

Mahmoud
