[Bug 273565] New: Digikam doesn't read EXIF if XMP sidecar file exists

https://bugs.kde.org/show_bug.cgi?id=273565

           Summary: Digikam doesn't read EXIF if XMP sidecar file exists
           Product: digikam
           Version: 2.0.0
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Metadata
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           2.0.0 (using KDE 4.6.2)
OS:                Linux

Hello.

I have turned on reading metadata from XMP files and writing XMP sidecar files.
It seems that in this case Digikam reads EXIF from the image only if there is
no XPM sidecar file. As soon as such file corresponding to the image is created
Digikam prefers to read metadata from it and doesn't read EXIF from original
image. At least there is almost no EXIF information in the sidebar. When I
delete XMP file or turn off reading metadata from XMP files all EXIF is shown
again.

I apologize if this behaviour is already known.

Reproducible: Always

Steps to Reproduce:
Turn on reading metadata from XMP sidecar file and create corresponding file.



OS: Linux (i686) release 2.6.37.6-0.5-default
Compiler: gcc

yes, we are here, but there are a lots of report to read. Please be patient...

Q: run digiKam in a console, with digiKam/Kexiv2 debug space enable using
kdebugdialog, and look all trace if any information are relevant of this
problem.

Also, metadata are managed in background by Exiv2. Can your reproduce the
problem with Exiv2 command line tool ?

I'm sorry, but I have reported this bug almost a month ago and I didn't know if
anybody has noticed it.

I don't think that there can be some problems with command line tool. All
metadata is available in the images because it is shown if I turn off reading
metadata from XMP files.

It seems that digiKam prefer to read metadata from XMP files and there is no
EXIF information but only XMP tags. And for some reason digiKam doesn't read
EXIF from the image if XMP file exists.

I'll try to run digiKam in debug mode later and see if there is some
interesting information.

I have launched digiKam in debug mode. I compared the output when "Reread
Metadata From Image" button is pressed for two images: with and without XMP
sidecar file. It seems that there is no important information, however, I can
provide it if you want.

I noticed another interesting fact. The same EXIF data is shown in Properties
sidebar for both images, but there is huge difference in Metadata sidebar. All
EXIF and Makernote information is shown for the image without XMP sidecar file.
However, there are only three lines in EXIF tab and no line in Makernote tab
for the image with XMP sidecar file. Note, that all information is shown again
after I turn off "Read metadata from XMP sidecar files".

Probably, all metadata is read properly, but it is not shown in Metadata
sidebar for the images with XMP sidecar files.

Should be fixed with the sidecar fixes applied for coming 2.6. Feel free to
reopen if there are still issues with current git (of digikam and libkexiv2)
