I cannot see why digiKam crash here.

Try with beta 2 and running digiKam under gdb...

Was this the dialog that is shown at startup (when splash screen is disabled)?
Or did you add the files in dolphin while digikam was running?

What is the '"Scan for files" device dialog.'? When you add images to digikam
while running it does not show any dialog.

I wish I could remember.  I just took a look at digikam and I couldn't find the
dialog, but it might have been the camera file dialog that I was canceling out
of.

Assuming this is fixed, no response for a long time and very old beta.
