[dev] git - printing from IMP in Firefox

[Rick Romero]

It seems to work fine in Chrome, but Firefox causes the following error:

  Fatal error: Call to a member function getElementsByTagName() on a
non-object in horde/imp/view.php on line 311

  This diff seems to fix it, but I'm not sure if that's a proper fix - it's
just too easy :)
