Comment 1 Kevin Funk 2012-12-20 23:11:12 UTC 
Please try to reproduce with current master. Code changed to much to match your backtrace.
Comment 2 argonel 2013-02-04 23:30:00 UTC 
Git commit ac6a4cdc673edd49a1784defce679673cef49eb7 by eli mackenzie.
Committed on 05/02/2013 at 00:26.
Pushed by argonel into branch '1.5'.

Avoid crash in showEditDialog if there is no patch

When instantiated by the plugin factory there is no patch available,
so a null pointer is used. Immediately after instantiation the tool
view is shown, which causes an attempt to access members through the
null pointer.
