Bug#21014: Segmentation fault of mysqldump on view

Browse Source 
mysqldump did not select the correct database before trying to dump
views from it. this resulted in an empty result set, which in turn
startled mysql-dump into a core-dump.  this only happened for views,
not for tables, and was only visible with multiple databases that
weren't by sheer luck in the order mysqldump required, anyway. this
fixes by selecting the correct database before dumping views; it also
catches the empty set-condition if it should occur for other reasons.
