https://freakattack.com/ KDE web browsers Konqueror and Rekonq appear vulnerable. Somewhat unclear though. If the browser is incompatible with the test site (this also happens if you download the site with wget or kioclient cp), it tells you to try https://cve.freakattack.com . This one does not load in KDE, while it does on my vulnerable android browser.
As you can see at https://cc.dcsec.uni-hannover.de/ the konqueror does support the vulnerable export ciphers. The allowed ciphers must be reduced for all kde programs using ssl/tls.

Works for me on Konqueror 4.14.13 and rekonq 2.4.2 using first link in description. (second link is no longer functional) (Ubuntu 14.04 32-bit) Someone want to close this bug?
