Sorry, I wasn't precise enough.

I opened a directory in command line, eg :
# showfoto mydir/

Then, I will get a blank "photo". If then I apply any fix or filter, showfoto will crash :

<<
QFile::open: No file name specified
QFile::open: No file name specified
showfoto: /tmp : RAW file identified
showfoto: Cannot load metadata using Exiv2 (/tmp: The file contains data of an unknown image type)
showfoto: Running dcraw command (digikamdcraw,-c,-w,-a,-H,0,-b,1,-q,0,-o,1,/tmp)
showfoto: Dcraw StdErr: Cannot decode /tmp
showfoto: Cannot load metadata using Exiv2 (/tmp: The file contains data of an unknown image type)

Apply any filter or any fix then, crash

KCrash: Application 'showfoto' crashing...

I did more tests and the problem is the same if you try to open a directory in "File/Open" instead of "File/Open folder".

But, the problem is not only that :

- if you open from cmdline any unsupported file or even a file that doesn't exist, you will get the same problem. Eg :
<<<
QFile::open: No file name specified
QFile::open: No file name specified
showfoto: /etc/passwd : RAW file identified

I also made some tests with a false jpeg file. Just create a text file and name it textfile.jpg
Open digikam ImageEditor on an invalid picture (textfile.jpg), you'll get an error :
Failed to load image "textfile.jpg"
But, this doesn't prevent you to apply any filter or fix
