124	exceptions when trying to use dirnode URIs	zooko	warner	"poor handling of user error: pasting a dirnode uri into the ""get file"" field of the wui

If you paste a dirnode uri into the ""URI of file to download"" field, you'll get:

{{{
An error occurred rendering the requested page. Additionally, an error occured rendering the error page.
}}}

The twistd.log contains:

Ah, the same thing happens when I paste the dirnode uri into the ""URI of new child"" field!

Here is the twistd.log from that:
