           Summary: Plasma Desktop Shell (kdeinit4), signal: Segmentation
                    fault
    Classification: Unclassified
           Product: kde
           Version: 4.10.1

I was mouse clicking the drop-down application menu for Thunderbird from the
task-bar at the bottom of the screen - method: hover over my Thunderbird
application icon, then when the drop down displays hover over that & mouse
click it.

The crash can be reproduced every time.

Unusual behaviour included complete blanking of screen, except for small
window, an applet, showing the wireless connection shortcut or at least its
logo, in top left corner that says for about a second, and then shows some
unusual behaviour - shows a box shaped field of coloured lines in the lower
right corner of the screen.  The computer always then restores itself to the
graphics screen (no5 of the 6 available) of my full monty pclinuxos
installation.


Reproducible: Always

Steps to Reproduce:
1. See "details" description above
Actual Results:  
1. See "details" description above

Expected Results:  
Open & go to active screen for selected application.
