           Summary: segfault with Samsung S85 RAW images
           Product: kipiplugins
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kde-imaging at kde.org
        ReportedBy: edelhard at debian.org


Version:           0.2.0~rc1 (using KDE 4.2.0)
Compiler:          gcc 4.3.2 from Debian experimental (i.e. the version is
guessed)
OS:                Linux
Installed from:    Debian testing/unstable Packages

The S85 is relatively new supported in dcraw. It always stores
.RAW *and* .JPG files and the .RAW doesn't contain any
metadata. Therefore dcraw has to open both files (that *may*
be part of the problem..) Anyway, when importing a .RAW to
digikam with kipi raw importer enabled (and also when running
dngconverter on a .RAW file) the apps crash. The Kcrash
handler doesn't show anything useful (i run the app in a
virtual xen machine with Debian experimental via ssh) but the
last trace messages on the console are:

Reading metadata from /root/Pictures/Landscape/SN850510.JPG ...
*** glibc detected *** digikam: double free or corruption (!prev): 0x08b2f8b8

=============== snip! ============= EOTrace =========

Plain dcraw from commandline and ufraw do work without
problems on these .RAW files.
Please contact me via PM if you need a sample image.

Greetings,
