Bug 206313

Version:           0.3 (using KDE 4.2.4)
Compiler:          gcc 4.3.4-1 
OS:                Linux
Installed from:    Debian testing/unstable Packages

Trying to drag / re-position a running System Monitor widget from right side of digital clock widget to other (left) side, resulted in SIGSEGV-11 in plasma

Why can't I re-position my widgets to be anywhere I like within a panel?  Why does KDE/plasma automatically place them and not allow me to re-order/rearrange them even I know the panel is not locked!

before this happened, plasma 0.3 was already taking up 50% of memory!! WTF?! I was trying to remove system monitor and then logout to rectify the memory usage but before I could logout and while dragging on System Monitor widget, plasma crashed. Now I have 2 instances of plasma still running while I submit this report.

This is my first ever bug report to the KDE organization. And I did not compile KDE 4 myself, I installed them via testing repositories into my brand new installation of Debian Lenny (which I dist-upgraded to Squeeze before installing KDE 4.2.4 deb's)

crash report follows:
