Description Tristan Deloche 2018-01-08 10:50:40 UTC 
Application: plasmashell (5.11.5)

Qt Version: 5.10.0
Frameworks Version: 5.41.0
Operating System: Linux 4.14.12-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:

Having two IntelliJ IDEA instances open at the same time and also Firefox (58) with a few tabs on a GPU-power starved machine (with RAM also clogged up from these) which apparently resulted in something not being done on time.

I tried adding the network monitoring widget which resulted in the task manager bar disappearing for about 5-10 seconds and losing access to the besktop for that same time (I guess that was a reset).

Not much of an expert regarding KDE, hope the attahced stacktrace is useful.

P.S. : Thanks for KDE it's pretty cool :)

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
