Alex, I don't get an exception in this case, but I see what you mean.
The plugin can easily determine the type of the following and provide
the appropriate method popup list. It should be an easy fix. Are there
any others I'm missing apart from these:

irb> {}.class
=> Hash

irb> "".class
=> String

irb> ''.class
=> String

irb> [].class
=> Array
