--- Comment #1 from Egmont Koblinger <egmont at gmail.com> ---
I can confirm the same behavior on Ubuntu 18.04 (konsole 17.12.3).

According to strace, tee is stuck in a write() call to its stdout
(/dev/pts/<number>) (this is the expected behavior if konsole doesn't read the
data), and so are od and dd back in the chain as they write() to a clogged pipe
(as expected).

Konsole is stuck in a futex(0x..., FUTEX_WAIT_PRIVATE, 0, NULL) call.
