This concerns right and middle clicking as well.

Additional steps to reproduce:

1. Open a folder containing few messages for the first time (no message selected yet).
2. Double/middle click on empty space below the messages in the thread pane.

Actual results:

Error console shows

Uncaught : Component returned failure code: 0x80550018 [nsIMsgDBView.getFlagsAt]
    _onItemActivate chrome://messenger/content/about3Pane.js:4577
    _onDoubleClick chrome://messenger/content/about3Pane.js:4545
    handleEvent chrome://messenger/content/about3Pane.js:4455

after double click,

Uncaught TypeError: can't access property "index", row is null
    _onMiddleClick chrome://messenger/content/about3Pane.js:4564
    handleEvent chrome://messenger/content/about3Pane.js:4460

after middle click.

Expected results:

Nothing should happen.
