           Summary: Saving large (>5M) jpg's result in corrupt file
           Product: digikam
           Version: 0.9.0-svn
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: jwest melaque com


Version:           0.9.0-svn (using KDE 3.5.3, Debian Package 4:3.5.3-1 (testing/unstable))
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.15-1-686-smp

When working with larger jpeg files (>5M) a save, or save as operation results in a corrupt output file.  This may be me, as I am using current svn compiled on a Debian (etch) system, but it is annoying.  If I fall back to 0.8.2 the file will save correctly.  In addition the file sizes are radically different (5.9M vs 4.4M)

digicam reports this during open and save:

I renamed the two files good/bad, and they are available here:
 http://www.melaque.com/bad.jpg
 http://www.melaque.com/good.jpg

jpeginfo command report on both files:

jwest fysm:~$ jpeginfo good.jpg
good.jpg 3008 x 2000 24bit Exif  N 597156

jwest fysm:~$ jpeginfo bad.jpg
bad.jpg  Corrupt JPEG data: 65519 extraneous bytes before marker 0xd9  JPEG datastream contains no image  [ERROR]


Apologies for not knowing how to debug this further.  
Thanks for any assistance.
