Application: digikam (2.4.1)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

Selected Import--> camera (select Canon detected automatically). then it crashes.
If lauching from a terminal, I read:
QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is still in use, all queries will cease to work.
KCrash: Application 'digikam' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/home/samuel/.kde/socket-PC-maison/kdeinit4__0

I installed the latest version by compiling it (I did exactly the commands given in http://www.digikam.org/drupal/download?q=download/tarball, no more, no less, as I don't know anything about compilation), because the version coming with the distribution (version 2.3 with Kubuntu 11.10) was not working (either...) for importing photos from a camera...

The crash can be reproduced every time.
