Bug 178765

Version:           KDE: 4.1.86 (KDE 4.1.86 (KDE 4.2 >= 20081221))  kdelibs svn rev. 901348 / kdebase svn rev. 901348 (using Devel)
Compiler:          gcc 
OS:                Linux
Installed from:    Compiled sources

Here using:

Qt: 4.4.3
KDE: 4.1.86 (KDE 4.1.86 (KDE 4.2 >= 20081221))
kdelibs svn rev. 901348 / kdebase svn rev. 901348
on ArchLinux x86_64 - Kernel 2.6.27.10

When trying to reproduce bug 177837
(This may be related to bug 172692, but as it's a different backtrace I'm creating a new report)

- Clear your Konqueror configuration (delete ~/.kde/share/apps/konqueror)
- Open Konqueror
- Go to Configure Toolbars
- Select Main Toolbar
- Add "Location Bar"
- Add "Go"
- Click OK
- Disable the "Location" toolbar (RMB on the toolbars, "Toolbars", disable "Location")
- Close Konqueror

Try to start Konqueror again. Crash! (you can't start Konqi again util you clean your Konqueror configuration)

Backtrace:

ASSERT: "id" in file kernel/qwidget_x11.cpp, line 751                        

Application: Konqueror (konqueror), signal SIGABRT
