It's not really a bug in the exporter, but rather a poor parser design
decision. Basically "info:emacs#Echo" is a valid link in Org, even as
a description of another link.

I removed nested links in parser. Instead I added a tool in "ox.el",
namely `org-export-insert-image-links' to add them whenever a back-end
can make use of them.

I made that change in master. So, the issue should be fixed there.

Thank you.
