[PATCH] Fix crash when closing a child document when outline and Pref dialogs are opened

[Abdelrazak Younes]

The reason is that closing a Buffer triggers an update of all opened 
dialogs when dispatching LFUN_DIALOG_UPDATE (hence the patch). The path 
is as following:

setBuffer() -> updateBufferDependent() -> RestoreButton() -> LFUN
The problem here is that the Toc dialog has not been reconstructed 
(because it comes after in the list of dialogs).

This patch should definitely go _before_ 1.5.0; OK?

Abdel.
