The 3d viewer may crash during initialization with some of its controls' connections on.
It can be solved by temporarily disabling the connections.
These controls are xcmaxslider, ycmaxslider and zcmaxslider.
Other controls are not applied the revision, as they don't cause crash in the current setting.
This is tested on Win10, with Qt 4.8.6 msvc2013.
