At startup, several of the toolbar icons are enabled when they shouldn't be. Clicking on most of them simply results in no action taking place, but clicking on the “Copy Database to Different Host” icon causes the application to crash.
Steps to Reproduce
==============
1. Start SQLyog.
2. Click the connect button (do not select any databases first).
3. Click the “Copy Database to Different Host” icon on the toolbar.
4. Watch application crash.
Note that after step two, the topmost host should normally be selected in the host/database pane, most of the menu items will be disabled, but several icons on the toolbar corresponding to disabled menu items will be enabled.
