Stencil Opacity Crash - 7.1.4

There is a specific sequence of actions that will repeatedly crash Rebelle 7.1.4

1. Add a Stencil to the image
2. Hide the stencil
3. Paint as normal
4. Unhide the stencil - but do not click to "apply" it
5. Open Edit -> Preferences -> Colour -> and adjust Stencils Opacity Slider / value
6. When you click Ok, Rebelle will immediately crash.

At stage 4, if you click to apply the stencil and/or start painting, steps 5 & 6 will not cause a crash.

Likewise, changing opacity while any number of stencils are hidden will not cause the crash.

Hope that makes sense

More specifically - if you try to change opacity while the stencil context menu is visible Rebelle will crash:
