Bug 402863

SUMMARY

If I run konsole for a while, usually several weeks, it suddenly stops copying text to the clipboard or primary selection. I select some text with the left mouse button and paste it with the middle mouse button but instead of the selected text I get something older which was selected previously. I can select whatever I want with the left button but I always get the same old selection with the middle button paste. It also doesn't matter if I use the Copy menu entry, same result. It looks as if the copy to primary selection function stops working. If I change the primary selection via some other means and paste into konsole I get the changed content. If I start a new window from the konsole File menu it inherits the broken copy. If I start a fresh konsole it works normal.


STEPS TO REPRODUCE
1. run konsole for some time, probably weeks
2. select some text
3. paste text into konsole

OBSERVED RESULT
some old selection is pasted

EXPECTED RESULT
the newly selected text should be pasted
