SCI: Hoyle5 (Hoyle Solitaire): Crash when changing volume

[OmerMor]

Using ScummVM daily build from 2017-13-01 13:06:25 (1.10.0git1663-g804058eb21).

Repro:
Start Holye Solitaire CD.
Start Card Flip mini-game.
Press "Options" button.
Move left volume slider.

Expected:
Volume change.

Actual:
Crash with the following message:
Uninitialized read for temp 1 from method volumeSliderToo::select (room 6029, script 6029, localCall ffffffff)!

In the same mini game (Card Flick), changing the hand speed slider will also cause a crash:

WARNING: Uninitialized read for parameter 1 from method Hand::add (room 6022, script 15, localCall ffffffff)!
Uninitialized read for temp 1 from method handSpeedSlider::select (room 6029, script 6029, localCall ffffffff)!

The call stack is:

...
GameControls::dispatchEvent
IconBar::dispatchEvent
flickingOptions::select
handSpeedSlider::select

... and not surprisingly, moving the 3rd slider (Coffee Level) will cause a similar crash:
Uninitialized read for temp 1 from method coffeeLevelSlider::select (room 6029, script 6029, localCall ffffffff)!
