But not when the lines aren't long? Interesting. Wonder if we can come  
up with a clever way to normalize how much text we look at, perhaps  
using wordwrap or strpos... would you create a ticket on  
http://bugs.horde.org/, including a sample message if you can?

There should be no other side effects.
