Sentry Crash Report:

Description Raghavendra kamath 2017-03-27 06:27:24 UTC 
Application: krita (3.1.88 (git cb56566))
 (Compiled from sources)
Qt Version: 5.8.0
Frameworks Version: 5.32.0
Operating System: Linux 4.10.5-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
To reproduce - 
1) open krita (built from svg/loading branch) and add a vector layer
2) add a vector shape like rectangle and also add a calligraphic stroke on same layer with calligraphy tool.
3) Now with select shape tool active draw a selection encompassing both calligraphic stroke and the vector stroke

Actual result - 
Krita crashes with below backtrace from Dr. Konqi

expected result - 
Both shapes should be selected and krita shouldn't crash

The crash can be reproduced every time.

-- Backtrace:
Application: Krita (krita), signal: Segmentation fault
