Description Ilya 2012-02-18 06:50:35 UTC
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

So, build dolphin plugin with debugging symbols. And are you using my patch?

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.
