Thikening the contour of an square crashes Impress

Hi,

recently I was preparing an lecture and I needed to draw an square around an
region of an image to get attention on that part of the image. When I try to
thiken the perimeter of the square crashes. I've tried on an new arquive
without any elements and it crashes as well. Anybody with the same problem?

I'm an user of Arch linux with kernel 4.1.6-1, Kde 4.14.11 (according to
kinfo) and my LO version is 5.0.1.2.0+ (buildID: 5.0.1.2 Arch Linux build-1),
Locale pt-BR(interface (en_US.UTF-8).
