Have used CR on older Android platforms and never had this problem, so I suspect it's 4.1/Chrome specific.
When attempting to follow the weblinks to the various archives, ":-1" is added to the host-part of the URL. E.g. "http://m.gutenberg.org/foo/" becomes "http://m.gutenberg.org:-1/foo/".
I was able to get to the Gutenberg catalog by editing the entry for it in the catalog list and adding ":80" to the host, but when I get into the catalog and attempt to download a book, it starts adding ":-1" again, I think because the catalog refers to an absolute path rather than a relative path.
For now I will work around this by downloading books manually in Chrome but thought y'all'd want to know.
If you need testing, please let me know, I'm more than happy to be a guinea pig. :^)
