Installed from:    Debian testing/unstable Packages
OS:                Linux

How to reproduce:

This reproduces the crash most of the time:

1) Click on an element, choose "chemical properties" in the popup window

2) close the popup window, and click on another element

3) when my mouse pointer reaches the chemical properties in the new popup, kalzium crashes immediately
