Version: 4.0.2 (using KDE 4.0.2) Installed from: Ubuntu Packages OS: Linux Repost of my launchpad bugreport <https://bugs.launchpad.net/kdebase/+bug/200997>: Binary package hint: konqueror-kde4 DISTRIB_ID=Ubuntu DISTRIB_RELEASE=8.04 DISTRIB_CODENAME=hardy DISTRIB_DESCRIPTION="Ubuntu hardy (development branch)" konqueror-kde4: Installed: 4:4.0.2-0ubuntu1 Candidate: 4:4.0.2-0ubuntu1 Version table: *** 4:4.0.2-0ubuntu1 0 500 http://archive.ubuntu.com hardy/universe Packages 100 /var/lib/dpkg/status If you open a text/plain file in Konqueror and go to e. g. a text/html website in the same tab afterwards, the website is displayed as text/plain, so you just see it's sourcecode. Tested with <http://update.warsow.net/warsow_last_version.txt> and then <http://www.warsow.net/>.
I can confirm this bug with kdelibs r786249
