Description Dario Andres 2008-12-14 20:51:36 UTC 
Version:           KDE4.2svn (kdelibs svn rev. 896844 / kdebase svn rev. 896844) (using Devel)
OS:                Linux
Installed from:    Compiled sources

Here using:
Qt: 4.4.3
KDE: 4.1.85 (KDE 4.1.85 (KDE 4.2 Beta2))
kdelibs svn rev. 896844 / kdebase svn rev. 896844
(today (20081214) build)

on ArchLinux x86_64

While trying to reproduce bug 158934 I experienced a Dolphin crash

Steps to reproduce:
-- Have Folders panel enabled in Dolphin

Now reproduce bug 158934:
(Insert a USB device , browse to some folders ("MediaDisk/Folder1/Folder2") inside it using Dolphin, safely remove the device.)

You get a location bar with non-existant paths. If you click on a non-existant item in the location bar (like "Folder1" in the example (as you are now inside "Folder1/Folder2") ), Dolphin crashes with the following backtraces:


Application: Dolphin (dolphin), signal SIGSEGV

If you need more information just ask me.
Comment 1 Dario Andres 2008-12-14 20:53:38 UTC 
More info: may be you have to click also in the "MediaDisk" item in the location bar in order to reproduce the crash.
Comment 2 David Faure 2008-12-23 01:38:18 UTC 
Possibly fixed by the fix for bug 177125? Can you update and retest?
Comment 3 Dario Andres 2008-12-23 02:04:45 UTC 
Seems to be fixed here using:

Qt: 4.4.3
KDE: 4.1.86 (KDE 4.1.86 (KDE 4.2 >= 20081221))
kdelibs svn rev. 900491 / kdebase svn rev. 900491
on ArchLinux x86_64 - Kernel 2.6.27.8

Good work ^_^. Thanks!
