Application: knotes (4.81 beta1)

Qt Version: 5.5.0
Operating System: Linux 4.1.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
With following example, filling, saving, reopining note, selecting text and
right-click anyware in note triggers a segfault. Note is marked as rich text,
not sure if the unicode part has anything to do with segfault. Triggering menu
without a selection doesn't cause the segfault.
Arch Linux kde-unstable packages (beta).
