[Bug 172680] New: Digikam crashes when I try to download the photos from my camera

http://bugs.kde.org/show_bug.cgi?id=172680

           Summary: Digikam crashes when I try to download the photos from
                    my camera
           Product: digikam
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


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.

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. :)
