I run konsole remotely (ssh -X othermachine konsole).

(The local and remote systems here are up to date Tumbleweed.)

This may seem an odd thing to do, but there are reasons why I find this useful
- in particular that I can open a new tab in the same directory that I'm
working in.

With recent Tumbleweed versions I find that a new konsole run this way will
become totally unresponsive for more than 10 seconds the first time that I do a
tab complete in bash inside it.

On the other hand, if the remote konsole is running on a remote Leap 42.2, I
don't see this issue.

Versions:

konsole-17.04.2-1.2.x86_64

Tumbleweed 20170626 (but this started to happen earlier - not sure exactly
when).
