unexpected exception by checking existane of plugins directory

[Shun-ichi Goto <gotoh@…>]

The line 71 of loader.py causes exception by {{{listdir()}} if 'plugins' directory does not exist. I think os.path.exists() should be used for this purpose.

Many users are trapped here, I guess.

You're right, I'll fix that.

I confirmed this issue is fixed, so I close by hand because commit action of [2010] didn't close it automaticaly.
