           Summary: Comments lost when converting from png to jpeg
           Product: digikam
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Kipiinterface
        AssignedTo: digikam-devel kde org
        ReportedBy: pave o2 pl


Version:           svn (using KDE KDE 3.5.8)
Installed from:    Unlisted Binary Package
OS:                Linux

Steps to reproduce:
1. Copy one or more png files (with comments stored only in digiKam database [as Exiv2 does not support adding them to png files]) to a new album. The comments are still shown with the new images.
2. Convert one or more images with kipi batch convert to jpeg(s).
3. Comments are lost on the new jpegs.
4. Update the comment on any of the png files (adding any letter and then hitting backspace suffices, it is only to enable "apply" when you hit pgDown/pgUp).
5. Convert photos to jpegs again (not necessarily the updated one!) - comments are preserved.

Once I encountered the same issue with jpg->jpg recompression, but wasn't able to reproduce it.

I was not sure if this is not a bug in kipi plugins, but it looks like it's digiKam who confuses the plugin.
