Description Oliver Putz 2008-10-27 22:29:37 UTC 
Version:           3.1.69 (using 4.1.69 (KDE 4.1.69 (KDE 4.2 >= 20081009)), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.26-gentoo-r1

Steps to reproduce:

1) Open kate
2) Go to Settings -> Configure Toolbars
3) Select main toolbar<katePartView>
4) change main toolbar<katePartView> (e.g. add a bookmarks menu)
5) Apply changes
6) See that the main toolbar was completely disabled
7) Right click on Menubar -> Check the box to show the "Main toolbar"
8) Now it gets a little more tricky...
8a) Go to Settings -> Configure Toolbars
8b) Select main toolbar<katePartView>
8c) change main toolbar<katePartView> (e.g. add a copy item)
8d) Apply changes

Sometimes it crashes right at that point, sometimes kate stays alive until I close it, sometimes it works out just fine... But normally I can make it crash after trying for like two or three times... 

Also depending on how I make it crash, the backtraces slightly differ. I only paste two sample backtraces as I guess all crashes have the same root cause...

Crash after closing kate after the above procedure

Application: Kate (kate), signal SIGABRT

Comment 1 Oliver Putz 2008-10-27 22:59:41 UTC 
Having reproduced similar crashes in other programs (e.g. kmail) and looking at the backtrace, it seems this might rather be a kdelibs issue than a kate issue...

General pattern: Adding and removing items from the "secondary" toolbar crashes the respective program

Comment 4 Dario Andres 2008-12-25 15:37:21 UTC 
I have reproduced this bug using Konqueror on:

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

---
After reproducing bug 169950

Steps to reproduce:

- Open Konqueror
- Browse to a website (ex. www.google.com)
- Go to Configure Toolbars
- Add the "Open in Firefox" icon to the main toolbar
- Open another Konqueror window in the default "about:konqueror"

- Close the "about:konqueror" window.
- Close the "www.google.com" window.

Konqueror crashes

(May be you have to try the lasts steps (may be in a different order) in order to reproduce the crash)

Also, due of bug 169950, the "Open in Firefox" icons dissapears after closing Konqueror, and after reloading it and going to "www.google.com" the icon appears in the Configure Toolbars dialog but not in the toolbar itself. (you have to move in the Configure Toolbars dialog in order to the icon to reappear in the toolbar)). So the situation may differs to reproduce the crash

Comment 5 Diego 2009-01-06 14:37:59 UTC 
As suggested by Dario Andres in this bug:
http://bugs.kde.org/show_bug.cgi?id=179710

I reproduced this bug on Konqueror too:
Version: 4.1.85 (KDE 4.1.85 (KDE 4.2 Beta2)) (using 4.1.85 (KDE 4.1.85 (KDE 4.2 Beta2)), 4.1.85-6.fc10 Fedora) Compiler: gcc OS: Linux (i686) release 2.6.27.9-163.fc10.i686

I spent some time trying to get how to reproduce it:
- it doesn't seem to depend on which button you add (I managed to reproduce it with "Undo: close window", "Open file..." and "New tab");
- it doesn't seem to depend on the position you place the button (I managed to reproduce it placing the button in the beginning, in the end and in the middle);
- it seems to happen more frequently when you press "Ok" rather than when you press "Apply".


Here's how to reproduce in my case:
Settings -> Configure toolbars
Add a button to the list and the click "Ok", if nothing happens then Settings -> Configure toolbars, remove it and press "Ok". If still nothing happens then retry again for some times. If still nothing happens then close Konqueror, reopen it and retry.

Here's my backtrace:
