Description Matthew Truch 2005-09-16 19:05:08 UTC 
Version:           1.2.0_svn_460893 (using KDE KDE 3.4.1)
Installed from:    Fedora RPMs
OS:                Linux

kst freezes when the clear button in the log tab of the debug kst dialog is pressed.

How to reproduce:  Open kst.  No need to plot any data.  Open the debug dialog, go to the log, press clear.

Expected behavior:  kst doesn't freeze.  I'd assume something like clearing the log would also happen, but I'm more concerned with kst not freezing.  ;-)

Note:  By freeze I do not mean crash (with a signal), nor do I mean some issue where kst is consuming all the CPU.
