Sentry Crash Report:

Description Juergen Karbach 2012-11-19 02:12:58 UTC 
This bug was  detected on to computers.
1. Desktop, OpenSuse 11.4 (Athlon 64-Bit), Digikam 2.90
2. Notebook, OpenSuse 12.2 (Intel DUO core-2), Digikam 2.6 and 2.9

Digikam crashes as soon as I try to import pictures from my connected camera (Canon PhotoShot SX 10IS. Camera ist detected by Digikam.
Happens both, if I select the import from the device plasmoid or from the Import menu. 
Happens with manually assigned camera and with camera detected by Digikam.
Happens with all my SD-cards. Normal (Canon)-mode and CHDK-mode.

SD-cards via USB-Reader working fine.


Reproducible: Always

Steps to Reproduce:
1. Connecting camera via USB and switching on.
2. Start import. Dosn't matter, if via digikam import or via KDE device control

Actual Results:  
The import windows appears an immediately disappears within a second.
Than digikam crashes "clean" - means you can restart digikam without any new bugs.

Comment 2 caulier.gilles 2015-06-30 08:07:29 UTC 
New digiKam 4.11.0 is available :

https://www.digikam.org/node/740

Can you reproduce the problem with this release ?
Comment 3 caulier.gilles 2016-07-15 16:29:52 UTC 
With digiKam 5.0.0, this problem is not reproducible.
I close this file now. Don't hesitate to re-open if necessary.
