Frameworks Version: 5.26.0
Operating System: Linux 4.11.0-1.g1b516a5-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
I started the Eclipse IDE from a folder widget on my desktop and then plasmashell crashed.

The next time I opened it, it worked.

The crash does not seem to be reproducible.

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