Description vanyossi 2014-06-19 19:08:44 UTC 
Make the source of a clone a group layer and a paint layer as the destination.

GDB
Program received signal SIGSEGV, Segmentation fault.

KisPaintDevice::defaultBounds (this=0x0) at /home/tara/nalaf/nala/program/calligra/krita/image/kis_paint_device.cc:365
365	    return m_d->defaultBounds;


Reproducible: Always



Expected Results:  
I was expecting it to clone the group layer contents but I understand why you wouldn't want to.
Cloning from a layer group to a child paint layer
Comment 1 vanyossi 2014-06-19 19:19:49 UTC 
No special setup.
Created group layer with 2 paint layer childs.
Select clone tool
Ctrl + click with the group layer highlighted
Select a paint layer outside the group (Ie background layer)
Crash

A little more detail on the backtrace.

Git commit 025c2020cd575f49ce13257ccf5bdd20294eb387 by Dmitry Kazakov.

Fixed crash when color picking from a group layer

Also fix all the pickers to read from projection() instead of paintDevice().
All nodes in Krita are expected to have projection() which is a visual
representation of the node in the stack.

The only new behavior this patch introduces is the picking from
Filter layers. Now it picks not from their 'selection' (which is
a paintDevice()), but from the filtered area cache (projection()).
