Subject: Unset QtCamdevice viewfinder when Viewfinder is being destructed.
X-Git-Url: http://cgit.sxemacs.org/?p=harmattan%2Fcameraplus;a=commitdiff_plain;h=937fe45637fd63dbd86a6d91ba3cd68c11cb7f28;hp=937fe45637fd63dbd86a6d91ba3cd68c11cb7f28

Unset QtCamdevice viewfinder when Viewfinder is being destructed.

This fixes the following crash:
pure virtual method called
terminate called without an active exception
Aborted

Viewfinder was being destroyed and QtCamDevice was still holding a pointer
to garbage. It tries to stop viewfinder when the device gets stopped
which leads to the above mentioned crash.
