Hi,
first some data about my system:

Krita 4.1.0 appimage
OS is OpenSuse Leap 42.3
AMD Quad Core 
Wacom Intuos 4 Tablet
Up to date Open GL Drivers

Description to reproduce bug exactly:
Open up Krita
Open a new or existing document
Choose a Brush (any Brush with Brush Tip option will do)
Open "Edit Brush Settings"
Click "Brush Tip" in the general section and click "Predefined"
Click (not drag) the "Size" slider. Size will change properly  
Drag the "Size" slider... Dialog box with error message pop's up 
Note: This error does not occur in Krita 4.0.4

Error message pop up:

Krita has encountered an internal error:

"m_d->lastKnownValue.isNull() || result == m_d->lastKnownValue" 
in file /home/appimage/workspace/Krita_Release_Appimage_Build/krita/libs/flake/KoDerivedResourceConverter.cpp, line 70
