Description Geoff King 2007-06-14 23:01:14 UTC

Version:           0.1.4 svn (using KDE KDE 3.5.7)
Installed from:    Ubuntu Packages
OS:                Linux

The latest svn update for the kipi-plugins slideshow seems to cause digikam final to crash up digikam exit.  It does not seem to affect digikam when it is running, but the Advanced Slideshow is not available in the menus.  

This seems to have started when the new feature 
"Images can be sorted/added/removed manually" was added yesterday.

A backtrace is below (let me know if you need me to recompile with debug options).  I just noticed that an identical bug report with more info is listed in the digikam-users list at http://mail.kde.org/pipermail/digikam-users/2007-June/003763.html

Comment 1 Gerry Patterson 2007-06-14 23:24:32 UTC

Hello,

It was my report mentioned on the digikam users list.  The only thing I have to add here, is if you actually create a slideshow and run it, digikam does not crash on exit.  If you start digikam and exit right away, digikam will crash everytime.

Something bad happens when one attempts to delete the member m_urllist in the plugin_slideshow class when the destructor is called.

Regards,

 Gerry
