Pre-B32 Right-click makes lua errors

[TheRani]

When I was trying out the pre-release for b32, I discovered that right-clicking on anywhere on the map, on anything at all, causes those "Oops, something went wrong, tell us what happened" things to pop up.

This bug still exists as of svn 4272.

To reproduce, simply to use the right-click menu when a talent isn't bound to a hot key and you'll get the following error:

Code: Select all
