Here's my attempt at getting something into PROBLEMS.

+*** KDE / Plasma 5: Emacs exhausts memory and needs to be killed
+
+This problem occurs when large selections contain mixed line endings
+(i.e the buffer has LF line endings, but in some parts CRLF is used).
+The source of the problem is currently under investigation, Emacs
+versions up to 24.5 just hang for a few seconds and then return with
+the message " Timed out waiting for property-notify event" as
+described in the previous note.  As a workaround, go to the settings
+dialog for the Clipboard widget and select the option "Ignore
+Selection".
+
+Note: Plasma 5 has replaced the separate klipper process from earlier
+KDE versions with functionality directly integrated into plasmashell,
+so even if you've previously did not use klipper this will affect you.
+Also, all configuration you might have done to klipper is not used by
+the new Clipboard widget / plasmoid since it uses it's own settings.
+You can hide the Clipboard widget by removing it's entry from the
+system tray settings "Extra Items", but it's not clear if the
+underlying functionality in plasmashell gets fully disabled as well.
+AT least a restart of plasmashell is required for the clipboard
+history to be cleared.

 This can happen if you have "Allow Primary Windows On Top" enabled which
