Application: krita (2.9.9)
KDE Platform Version: 4.14.20
Qt Version: 4.8.7
Operating System: Linux 4.5.4-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
After starting the application, I created a new document using the default presets (1600x1200 px, 100 ppi, etc). I then used the text tool to create a vector text layer which gets filled with the placeholder text "Artistic Text". I pressed CTRL + A to select all of this text content. Then, on hitting any key to replace the placeholder text with something else, the application crashed immediately. This is fully reproducible. Just modifying the placeholder text (font size, text properties, etc) does not crash Krita.

The crash can be reproduced every time.

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