http://bugs.gentoo.org/show_bug.cgi?id=367943 http://bugs.gentoo.org/attachment.cgi?id=273863&action=edit Attachments get text/x-log Mimetype instead of text/plain, thus they won't show up in browser directly anymore. Very annoying.
While I probably should make a separate bug for it, somewhat related might be an another minor annoyance - as I noted in many bugs (last time in bug 367613), double gzipped attachments became frequent lately.
The auto-detection is currently done by your browser itself, bug 366161, esp. #c11. *** This bug has been marked as a duplicate of bug 366161 ***
