potential issue with s:viewer in compiler.vim

[tianzhuqiao]

I install vim-latex on a Mac. When I use "\lv" to open the compiled pdf file, it shows the error message:

Error detected while processing function Tex_ViewLatex:
Line 34:
E121: Undefined variable: s:viewer
E116: Invalid arguments for function strlen(s:viewer)
......

It looks like the "s:viewer" variable may not always be defined in compiler.vim?

If I add the following line at the beginning of compiler.vim, the problem goes away.

let s:viewer = ''"

Thanks
