Description illogic-al 2006-06-25 22:34:39 UTC

Version:           4.5.2 (using KDE 3.5.2, Arch Linux)
Compiler:          Target: i686-pc-linux-gnu
OS:                Linux (i686) release 2.6.16-ARCH

This problems described below appear on the version of KWrite accompanying KDE 3.5.2. 
Steps to reproduce
1. Open a file in kwrite (The one I've been using is ~/.kde/share/config/kdesktoprc) and edit it.
2. Save the change
3. Cause a change to happen outside of the program. The way I do this is by going to KControl -> KDE Components -> File Manager and changing the [] Display file sizes in bytes checkbox and then pressing the Apply button.
4. Go back to the KWrite window. In my example kdestoprc will have been changed outside the program and the  "File Changed on Disk" dialog will appear. 
5. Choose the "Reload File" option
6. Go back to the KDE Control Module and change a different setting. What I did was to go to the Previews and Meta-Data tab and increase the "Maximum file size: " slider. After making a change press the apply button.
7. See Kwrite go boom.

You should only need to repeat steps 4-6 twice more, at most to observe this crash. 
a) Please test exactly as listed before saying this bug is no longer present (in 3.5.3 or svn). b) Feel free to add a better backtrace.
