Description wolthera 2017-07-02 17:13:07 UTC 
Application: krita (4.0.0-pre-alpha (git 10f436f))

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.8.0-56-generic x86_64
Distribution: KDE neon User Edition 5.10

-- Information about the crash:
When using the shape selection tool, to access the booleans, we need to "rightclick" or rather, we need to summon the pop-up palette.

However, I connected the pop-up palette to key ";" instead of rightclick.

This causes this crash to happen.

The crash can be reproduced every time.

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

Git commit c6506bb9af659f780aff4d8109a48fe12e52b36a by Boudewijn Rempt.
Committed on 21/11/2017 at 09:05.
Pushed by rempt into branch 'master'.

Do not crash when opening the palette with a keyboard shortcut

When an action is triggered by a keyboard event, the event
passed is 0:

retval =  tryRunSingleActionShortcutImpl(key, (QEvent*)0, m_d->keys);

So we need to check whether the event is valid.
