Comment 1 Frank Reininghaus 2008-09-16 19:29:55 UTC

Thanks for the bug report. I cannot reproduce this because I get a "URL cannot be listed" error, but the backtrace looks very much like it's a duplicate of bug 160057.

Comment 2 Jonathan Thomas 2008-09-18 14:00:51 UTC

Do you have kamera from kdegraphics installed?

Comment 3 Frank Reininghaus 2008-09-29 23:46:30 UTC

Thanks for the hint - after installing libgphoto2-2-dev (needed by kamera) and rebuilding kdegraphics I don't get the error message anymore, but I don't get a crash either. Does it happen in any view mode for you? Do you need to have previews enabled?

If this can be reproduced by someone running trunk >= rev. 865153, it might be helpful to have the error message starting with "First item has URL" which is now printed before that assert is hit.

I'm CC'ing David who has been working on a few bugs with the same backtrace recently.

Comment 4 David Faure 2008-10-01 23:27:49 UTC

I guess one also needs a digital camera plugged into the computer :)

Comment 5 Jonathan Thomas 2008-10-01 23:29:24 UTC

It crashes for me without any camera attached to the computer.

Comment 6 Frank Reininghaus 2008-10-01 23:41:05 UTC

I forgot to mention in my last comment that I tried both with and without camera plugged in - I can't get a crash in either case. I can't access the pictures in the camera though - opening "camera:/" shows a folder named like the camera, but opening this just shows me another folder with the same name which cannot be opened. Works fine in Kubuntu's KDE 3 versions of Dolphin&Konqueror, but that should probably be filed as a separate report...

Comment 7 Jonathan Thomas 2008-10-16 19:18:55 UTC

Seems fixed in 4.1.2.
