Bug 184580

Version:           1.7.0 (using KDE 3.5.10)
OS:                Linux
Installed from:    Ubuntu Packages

I'm trying to write a script to configure tabs and plot objects based on a hardware map instead of setting this up manually from menu options every time our hardware setup changes. I have a class that gets the data, gets the power spectrum of the data, creates a tab and places plots for the data and PS. This works fine when I run one instance of it, but crashes kst when there are several tabs being created. I have noticed that it works much better, though still occasionally crashes, when I am not generating the PS objects.

Any help would be greatly appreciated. I could send the scripts to anyone who would be willing to look at it.

Thanks.

The backtrace gives me this:
