Yeah, it fixes the crash, but I assume it breaks some functionality (related to
restoring a session with search active, I guess). That's why I tried to add
some singleShot() hacks in setSearchModeEnabled() that called
setSearchModeEnabled() again if the pointer was null, to try to recover.

The check is done in disconnectUrlNavigator() because that nulls out the
pointer again iirc.
