Bug 207048

Application that crashed: ksysguard
Version of the application: 4.3.00 (KDE 4.3.0)
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30.5-43.fc11.x86_64 x86_64
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
This is a bug in "KDE System Monitor" version 4.3.00
Here is how to reproduce this bug :
-open "KDE System Monitor" (i do this from kickof menu)
-go to "System Load" tab
-right click on "Network History" graph
-clic "Proprieties"
-clic "Scales" tab
-clic uncheck "Automatic range detection"  check box
-change "Maximum value" to 128
-clic "Ok"
CRASH

It seams the program crash because we unchecked Automatic range detection.
I tried different values and it keep crashing.
This check box is not checked by default for "Memory and Swap History" and "CPU History", I tried to check it, uncheck it change the values for both of them but the program doesn't crash.
Thanks KDE team for your great job :)
I am not really a good programmer, but I will be happy to help this project by developing, testing or just reporting bugs :) keep going forward, good luck :)
