Description robn.l25 2010-11-26 14:10:30 UTC

Application: dolphin (1.5)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

draging one or more files out of dolphin (for example vlc's playlist...)
Dolphin crashes at the moment where the mouse leaves the application's main window.

The problem started with smb:// files and can now be reproduced with local files.

- Custom settings of the application:

I'm not using kde4 environment: my environment is LXDE+Openbox

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault

[Comment from a bug triager]
- Do you have some kind of window compositing/ effects enabled ?
- Could you try this on a full KDE session to try to determine if the LXDE+OpenBox combo is related to the crash ?

There are several drag-and-drop related crashes reported for Dolphin and most of them point to the Qt libraries.. However we couldn't reproduce any of them in a reliable way.
(bug 203887 as en example)

Thanks

Comment 2 robn.l25 2010-12-17 02:37:35 UTC

There is no window effects enabled.

I made some tests :
full KDE : 5 minutes drag&dropping files : no problem
KDE/openbox : no problem too
LXDE/openbox : dolphin crashed instantly when the cursor arrives on the desktop wallpaper.
dragging files from one dolphin instance to another one won't crash if I do not let the cursor meet the wallpaper. (I hope the sentence is understandable...).

The problem seems to be linked with the LXDE session. Maybe we should test with another one (xfce...)

Note that all dolphin's instances opened in the same session crashed when the segfault arrives.

Thanks for considering the problem.

- What are the Dolphin view modes ?

I just tried on LXDE+OpenBox and two Dolphin windows (default settings) but I couldn't reproduce yet

Regards

Comment 4 robn.l25 2011-01-20 19:59:10 UTC

Sorry for elapsed time...

Dolphin's configuration is default one with "details" view, use the same display parameters all folders and filter bar.

I notice the problem after installing proprietary nvidia drivers.
All my three computers have a nvidia graphic card and they all have the bug.

If I have more time, I will try with another graphic card.
