Since BufferList 1.2 right-clicking a directory and chosing any buffer based action like save or close does not work anymore. The attached patch fixes this.
Patch is against revision 21840 (as of 2012-06-21).
Fix for #3307762?
Yep, it is a fix for 3307762.
If you want to help some more, please review some of the other unassigned BufferList tickets. I will try to prepare a release for the next month or so.
Thanks for your contribution!
