[Bug 242937] New: When using raw import tool, showfoto cannot export the processed image

https://bugs.kde.org/show_bug.cgi?id=242937

           Summary: When using raw import tool, showfoto cannot export the
                    processed image
           Product: digikam
           Version: 1.3.0
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: RAW files management
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.3.0 (using KDE 4.3.5)
OS:                Linux

If option "use raw import tool" is enabled on Preferences -> Configure ShowFoto
-> General (I'm translating from Spanish), it is not possible to export the
resulting image. An error message "Impossible to save <file_name> on
<file_path>" is displayed, no matter which file or which path.

Reproducible: Always

Steps to Reproduce:
1- Enable the raw import tool
2- Open a raw file
3- Try to "save as" it as, say, png

Actual Results:  
An error message is displayed

Expected Results:  
Processed image should be exported

Digikam and kipi plugins packages are from kde:community repo on openSUSE 11.2.
System is 64 bits

Created an attachment (id=48390)
 --> (http://bugs.kde.org/attachment.cgi?id=48390)
Konsole output when trying to export the raw image

I launched showfoto from konsole with
showfoto file_name.nef
and without doing anything to the image I tried to export the raw image as png,
obtaining the error message. In the attachment you can find the output.

There is nothing to see in your trace.

Do you tried to export to TIFF or JPEG. It work ?

Which libpng version you use ? Go to Help/Components Info for details. Do you
have more than one libpng on your computer ?

I forgot to mention. When the "save as" fails, an empty file is created in the
image folder with a name similar to dC5529.digikamtempfile.tmp
The folder is on my home directory so there is no permission problems, there
are no accented characters on the path... nothing strange.
I also deleted showfoto config file and started from zero, without changes.

Ah. This point is important. This problem is not linked to libpng. It's temp
dir/file creation problem.

Now run kdebugdialog and turn on all digiKam and Showfoto area to see all
debugs statement in the console. Restart showfoto, and give me the trace.

Created an attachment (id=48398)
 --> (http://bugs.kde.org/attachment.cgi?id=48398)
Showfoto with debug packages and kdebugdialog running

I installed the debug packages for digikam (debuginfo and debugsource), run
kdegubdialog and then run showfoto the same way as before.
Something I just noticed is that when I press the "save" button, the only line
added to konsole output is
QImage::scaled: Image is a null image

Can you please attach the raw photo you are using to the bug, or if it is too
big, upload it somewhere one a file sharing service.

Before to save item, you need to press "Import" button on right bottom sidebar.

Note : it's abnormal to see all menu item enabled when Raw Import Tool is
loaded. This is only reproducible with showfoto, not digiKam image editor.

It's relevant to all toggleActions(true) in showfoto.cpp. This behavior is
valid if you load an image directly, without to pass by a tool as raw import. I
will fix it.

Thanks for the clarifications, now I understand how this work. But I must say
that the "Import button" is somewhat misleading: I'm SEEING the image inside
ShowFoto, and the changes I make are applied to the preview when I click
"Update": as a new user, how can I guess I need to import the image AGAIN? I
considered the "Import button" as something I should explore once the "Save as"
problem was solved...
Also, the error message was not very helpful.
But well, now it is working! Thanks for the patience and sorry for not
exploring deep enough before submitting the bug report.
