ChangeSet
  1.1957 05/11/11 19:06:18 SergeyV@selena. +1 -0
  Fixes bug #14569. In addition to check current db of not being NULL value 
  it is added a check of not being empty value. When modifying SP with Admin 
  application on win32 it does not pass curent database so sp is stored with
  db=null which causes a crash later on show procedure status;
