Version: (using KDE 4.1.2) Compiler: gcc 4.3.1 OS: Linux Installed from: Gentoo Packages I'm experiencing a crash when I try to download the photos from my camera when using the following two configurations: - digiKam 0.10.0 beta 2 on Qt 4.4.2/KDE 4.1.2 - digiKam 0.10.0 beta 4 on Qt 4.4.2/KDE 4.1.2/libkdcraw from kdegraphics 4.1.69 Everything is compiled with gcc 4.3.1 and is running on a x86_64 machine. The crash occurs at the moment I try to open the camera (e.g. I click on it in the main menu). After this, the camera is inaccessible from other applications until I reconnect it, or turn it on and off. A subsequent try to open it from digiKam without doing so, doesn't result in a crash, just it waits indefinitely for the camera, until I close the window. The camera is Nikon D200 running in PTP mode. I will attach a backtrace shortly.

Marcel, Look like there is a lock with database when a new file is insserted in album collections... Gilles Caulier
We must pay attention, this can be misleading: The thread backtrace which sends the abort is clearly because of a locked db that should not be locked, but looking at the main thread backtrace, you see that it is attempting shutdown out of the middle of operation because of an XIO Error caught by KApplication. I found this message regarding the topic: http://lists.kde.org/?l=kde-devel&m=121673396224505&w=2 where it is suggested to run the application with the --sync option to possibly get more information.
We recently fixed a crash in the gphoto code which could be the cause of this. Can you please retest with current svn or beta6?
The crash doesn't happen with me anymore with beta6, so I'm almost certain that at least my crash got fixed, so now I can download photos without any problem. Thanks. :)
