I have made almost no changes as of yet. Just trying to figure out what 
causes the crash.

I noticed in pcbnew/tools/edit_tool.cpp cutToClipboard that the method 
does not cause a crash If i only run on of the two method calls in it. 
Doesnt matter which one I remove, I also noticed that the crash is due 
to a CN_ANCHOR not being valid.

#4  0x00007fffe5cd1ab3 in CN_ANCHOR::Parent (this=0x5555588178a0) at 
/home/krille/projects/kicad/pcbnew/connectivity_algo.cpp:924
924	    assert( m_item->Valid() );
(gdb) p *m_item
$1 = {<INTRUSIVE_LIST<CN_ITEM>> = {m_count = 1484021408, m_prev = 
0x670000006e, m_next = 0x2200000020, m_root = 0x6c00000025}, 
_vptr.CN_ITEM = 0x55555753f9c0, m_parent = 0x2200000073, m_connected =
