            Bug ID: 325830
           Summary: Panorama Stitcher returns an error after
                    pre-processing, as a result of attempting to invoke
                    Hugin commands
    Classification: Unclassified
           Product: digikam
           Version: 3.4.0
          Platform: MS Windows
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: Kipiinterface
          Assignee: digikam-devel at kde.org

The issue is Digikam Panorama stitcher fails after pre-processing to execute
the Hugin files needed.  I continually get an error message.
I'm using:
Windows 8 64 bit (but does the same with Windows XP sp3)
Digikam 3.4.0 (but failed exactly the same on  3.3.0)
Hugin 12.0.0

Everything goes well  through pre-processing, then, I hit  next and it
processes for  a very short  time and  comes back with the following:

ERROR


Cannot run C:/Program Files/Hugin/bin/make.exe:
'C:/Program Files/Hugin/bin/nona.exe' -z LZW -r ldr -mTIFF__m -o “preview” -i 0
“C:/Users/Jim/AppData/Roaming/.kde/tmp-ACER “C:' is not recognized as an
internal or external command, operable program or batch file.
Make: ***[preview0000.tif]Error 1

It seems to me that the directory and file delimiters for windows are wrong and
these command lines should look more like  this

C:\Program Files\Hugin\bin\make.exe
C:\Program Files\Hugin\bin\nona.exe -z LZW -r ldr -m TIFF__m -o “preview” -i 0
C:\Users\Jim\AppData\Roaming\.kde\tmp-ACER-PC

At least as far as the delimiters are concerned.

It looks like a command and parameter string being sent to the Windows command
processor to run "make" and "nona" and pass parameters to the program, but the
back slashes in the folder\file structure are telling the command processor
that "C:" is the program to run and the rest are parameters to pass.

The initial start-up of the panorama stitcher acknowledges the Hugin files with
a green check on each.  I tried re-browsing each one and also tried dumping the
whole Hugin bin contents into Digikam bin file and re-associating them, but
neither worked.  Each method showed a green checkmark, but the same  error
message.  I uninstalled and  reinstalled Digikam to remove my file transfer,
then looked into the windows registry to see the file associations were stored
there, but no luck finding anything I could correct in the registry.  I tried
to find a readable database the paths may be stored in, but gave up. I'm now at
a loss.

Hugin creates panoramas just fine, so I don't think it has anything to do with
their programs and I cannot find this specific issue on the internet.  

Reproducible: Always

Steps to Reproduce:
1.select files to stitch and launch stitcher from drop-down menu
2.use default options (or not) and select next
3.after pre-processing, select next
Actual Results:  
Error message:
select cancel

Expected Results:  
Produce the panorama

Different options seem to make no difference.
