Application: plasma-desktop (4.11.11)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.19.0-32-generic x86_64
Distribution: Linux Mint 17.3 Rosa

-- Information about the crash:
Okay here's what I was doing:

I have a dual montor setup I've been playing around with under Mint 17.3, I have my main montior set up using the "folder view" and I had just switched the secondary one to "grouping desktop". On that one I have the vaired widgets that act as system montors (CPU, RAM, etc).

I went to resize the Temperature one by lift-clicking on the widget and grabbing the  re-size box on the toolbar that shows when you click on the widget (upper most item). Plasma crashed when I went to select it (I think I clicked and started to drag to resize).

My video card is a Nvidia GeForce GT 610 (GF119) using the x_86_64 353.63 "updates: driver installed via the "Additional Drivers" tool. I have a "custom" system with an AMD-4100 FX CPU and a  ASRock 960GM/U3S3 FX mobo, 8 GB of RAM.  I have installed a WD Black 1TB HHD (Windows runs from that) and a Seagate 3 TD drive that my Mint is on. System partition is ext4 and I have a "data" one formated btrfs (yeah I know). I thought that might be import.
