Well, it's hard to this report as it's difficult to reproduce but it happens at least once or twice a day (according to whether you are typing a lot or not), but I observed it since a few months, and is still there.

Sometimes happens that konsole hangs (like when you were pressing a scroll-lock key) while you are typing text and you are on the *last line* of the konsole. At this point you can't type anything further. Only thing which sound to do some activity is the "clear scrollback and reset" from the View menu, but it will just clear the current konsole and no further typing or activity is allowed anyway. Also on the File menu adding a "new tab" would fork a new working konsole tab.

There are no other strange behaviour in logs, or crazy processes that eats 100%. Very hard to debug. This reminds me a similar bug that was happening on the AmigaOS on its console, in the same circumstances, i.e. when you were typing on the last line of text.

Suggestions?
