Comment 3 Dominik Haumann 2012-02-19 08:36:27 UTC 
Bug #282995 also reports this issue in KDE 4.6 (with test case!). Hence, this is an old bug, still exiting in the new code folding.
Comment 4 Dominik Haumann 2012-02-19 08:38:24 UTC 
Erik, can you please attach a test case? Along with a detailed description what you type in which line/column?
