Bug 306326

Application: kmail (4.9.1)
KDE Platform Version: 4.9.1 (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.5.1-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

-- Information about the crash:
- What I was doing when the application crashed:
* add a spreadsheet shape to an empty document
* double click to activate it
* double click a cell to start the editor
* close words with the opened Editor.

The root is, that CellEditor sets d->selection to cellEditor->selection() upon construction, but references it in its destructor AFTER the cellTool (in this case a TableTool) got destroyed.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
