Subject: kget: reject URLs without filename from UrlChecker
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=dd65c28c4965d5ab602145d11b1002d44f03c074;p=kde%2Fkde-extraapps.git

kget: reject URLs without filename from UrlChecker

this will reject URLs such as https://foobar.com/ because kget cannot
handle such even tho KIO can get the page content (without the filename
component there is no telling what kget should save the URLs as, the
destination has to completed with filename manually)
