Application: karbon (2.6 Pre-Alpha)
KDE Platform Version: 4.9.00 "release 558"
Qt Version: 4.8.2
Operating System: Linux 3.4.6-1.1-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
Create a new document, then use the layer docker to create a new layer.

I suspect this is fall-out from the document/view/part split refactoring.

The crash can be reproduced every time.

-- Backtrace:
Application: Karbon (karbon), signal: Aborted
