It appears to be a problem with the extension (*.sea.hqx):
 * foobar.bar.baz cause no problem
 * something-else.sea.hqx also cause problems

It appears to be ff (or gecko?) specific
 * bug detected in this version of ff (Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1a1pre) Gecko/2008060902 Minefield/3.1a1pre), ff2, ff3 (in *buntu repositories) 
 * ff under wine also cause this problem
 * ff in winXP cause the same problem
 * ff on macOSX cause the same problem
 * in dillo (ubuntu), safari (macOSX), explorer (winXP) the file is treated like any other file and I am offered to download it
 * epiphany (2.22.1.1, gecko-1.9) seem to also have the same bug

NOT TESTED:
 * I have not tested if *.hqx files in general cause problems.
 * I have not tested *.sea.* files.
 * I have not read http-request-header-mumbo-jumbo sinse I know nothing about it.
