kde4base-konqueror-4.4.5-alt0.M51.1 doesn't treat the page at https://www.tcsbank.ru/credit/form/ correctly:
after filling out the application form and pressing the button to submit the data ("Оформить карту" or smth like that), blank screen is shown.
Expected: some infomration about the result of your action should appear.
(It's not clear whether this is a problem of the browser or of the site. I'll write about this problem to the site administrators as well -- http://www.tcsbank.ru/about/contacts/ .
BTW, chromium-browser-7.0.513.0-alt1.r58159 treats this page even worse: it shows a blank screen immediately after opening he page and showing the form for an instant.)
А они уже исправили веб-страницу сами. ;-)
