Shows the error page in case an exception is raised while drawing the contents.
Descendants should override _drawContents, not updateContents.
During the call of _drawContents, the updating of the configuration tree is blocked to
avoid circular effects. After that, a call to self.config.refreshFromTarget() is
made to refresh the configuration tree with possible new values from the inspector
(the inspector is the configuration's target, hence the name).
The reason parameter is a string (one of the UpdateReason values) that indicates why
the inspector contents whas updated. This can, for instance, be used to optimize
drawing the inspector contents. Note that the reason may be undefined (None).
The initiator may contain the object that initiated the updated. The type depends on the
reason. At the moment the initiator is only implemented for the "config changed" reason. In
this case the initiator will be the Config Tree Item (CTI that has changed).
