Hi

Can you please clearly give "Steps to Reproduce"? It is not clear when does it exactly crash on your system.
Comment 2 dinhptra 2012-05-01 19:09:53 UTC 
1. Start Digikam
2. Choose an album with a few pictures in it
3. Click on "Slideshow" --> "Advanced Slideshow" --> "Start Slideshow"
4. Crash
Comment 3 Smit Mehta 2012-05-02 03:27:19 UTC 
Hi

I confirm it. Although, instead of segmentation fault, I am getting digiKam PID : 12038 Signal Aborted(6)

Here is the backtrace :

Comment 4 caulier.gilles 2012-06-22 08:55:54 UTC 
Official Kipi-plugins 2.6.0 release is out since few days now :

http://www.digikam.org/drupal/node/656

Please, check if this entry still valid, or update report accordingly.

Thanks in advance.

Hi "dinhptra@gmail.com"

You can test it out with latest kipiplugins (>=2.9.0). We are not able to reproduce it here anymore, and hence I believe it is fixed. In case you are still able to reproduce it with the latest versions, you are welcome to re-open / file a new bug.
