Comment 1 Christophe Marin 2011-08-28 17:52:22 UTC

Cannot reproduce, please retry with KDE 4.7.1 (opening the links you gave in konqueror and using the webkit engine should be enough to test this)

Comment 2 Denis Kurz 2016-09-24 19:40:00 UTC

This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present?

If noone confirms this bug for a Framework-based version of akregator (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months.

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
