Description Francesco B. 2013-11-18 03:45:35 UTC

Using Sketch_ink_big brush crashes krita after one or few strokes when the imput comes from a tablet (I have a wacom bamboo MTE-450). It doesn't happens with the mouse.

Reproducible: Always

Steps to Reproduce:
1. Create a default 1600x1200 100ppi 8Bits RGB canvas.
2. Select Sketch_ink_big brush. 
3. Start drawing without lifting your pen from the tablet.
Actual Results:  
Krita crashes at the start of the stroke or after few seconds of continuous drawing (i.e. WITHOUT lifting the pen from the tablet).

Expected Results:  
Not crashing.
