Description wolthera 2016-09-11 21:37:29 UTC 
1. I was painting
2. then I tried to pan, but made a mistake: it wasn't a pan action, but a painting action.
3. I undo my stroke.
4. I pan.
5. I see a guide. I think to myself "that guide shouldn't be there, let's remove you, guide"
6. Upon trying to drag the guide, Krita crashed.

Reproducible: Didn't try
Comment 1 Halla Rempt 2016-09-15 13:09:51 UTC 
This is probably going to be impossible to fix and very hard to reproduce. Looking at the code

bool KUndo2Command::timedMergeWith(KUndo2Command *other)
{
    if(other->timedId() == this->timedId() && other->timedId()!=-1 )
        m_mergeCommandsVector.append(other);
    else
        return false;
    return true;
}
The only way this could happen is if either the this or the other pointer is deleted. Neither is zero.
