Version: (using KDE 4.2.98) OS: Linux Installed from: Ubuntu Packages 1. Open any html page with multi-line input field. Let's suppose you have some text in your clipboard. 2. Type fast something like "aaaa aaaaa aaaaa aaaaaa aaaa" and then press Ctrl+V. 3. Press Ctrl+Z once. 4. Oops: all text you just typed disappers! Expected bahaviour: only past operation is undone, all text I have typed should be still here. I believe Ctrl+Z should undo only last operation (Paste). Kate works exactly like I expect.
To be clear: typed text is irrelevant, you just need to type something :)
The same bug can be reproduced on the kmail composer. Probably it is a problem on Qt or kdelibs.
Still here in 4.4.3
Does not reproduced in 4.4.5
