Application: dolphin (2.0) KDE Platform Version: 4.8.00 (4.8.0 Qt Version: 4.8.0 Operating System: Linux 2.6.37.6-pae i686 Distribution (Platform): Archlinux Packages -- Information about the crash: - What I was doing when the application crashed: When i go to my SMB Public folder, and want to create new Folder. I click right button on a free space, and getting the crash. KDE Base compiled with Debug mode, and without strip option. I suggest, that bug is in the Dropbox plugin, but Dolphin, IMHO, must catch following errors, but not crashing. I'm specially do not update box-plugin from aur, to give you a valid backtrace The crash can be reproduced every time. -- Backtrace: Application: Dolphin (kdeinit4), signal: Segmentation fault Using host libthread_db library "/lib/libthread_db.so.1".

Git commit c06dae12ff85b0c2b9381b2e35c7553b77be8706 by Peter Penz. Committed on 27/04/2012 at 09:28. Pushed by ppenz into branch 'master'. Never pass null-items to version-control-plugins Some plugins are not prepared for this and might crash. Although the additional check in VersionControlObserver::actions() should not be necessary because of the fix in DolphinView, it is left here to catch potential other cases where a null-item might get passed accidently. Thanks to Ilya for initially patching the Box-plugin which gave a hint whats going wrong.
