New crash information added by DrKonqi

plasmashell (5.5.0) using Qt 5.5.0

- What I was doing when the application crashed:

Go to Dolphin settings, Services tab. Enable Activities service (to associate activities with files). In Dolphin right click mouse, hover mouse on Activities menu entry in context menu. Dolphin crash without notification. Then right-click in Desktop Folder View widget on some folder, hover mouse on Activities menu entry in context menu. Whole Plasma crash and restarts. This error notification appears.

I cannot reproduce this but, it works flawlessly. Icon theme installed, no crash.

plasmashell version 5.4.2
Comment 5 opensuse.lietuviu.kalba 2016-01-13 08:32:11 UTC 
I can no longer reproduce in KDE Plasma 5.5.3

P.S. StarSapphireKDE incon theme description has warning about high RAM usage

How to reproduce - video (webm)

But I can reproduce in KDE Plasma 5.5.1 with similar backtrace (drKonqi says it is the same bug!) using another instructions:
1. in Dolphin enable "File to activity linking plugin"
2. rigth-click at any file/folder a) in Dolphin b) or in desktop folder widget
3. hover mouse over Activies context menu
