Description Erik Quaeghebeur 2020-03-25 21:19:30 UTC 
SUMMARY
I was using krusader to copy files from one sftp directory (on one server) to another (on another server). After a few files, I get an error message that a file couldn't be saved. Then a message is displayed saying that an ‘internal error’ has occurred and that I should file a bug. Looking in the logs, I see the following suspicious line:

kf5.kio.core: finished() called twice! Please fix the kio_sftp KIO slave

(This is repeated, probably because I tried a number of times.)

The issue is reproducable.

Comment 1 Harald Sitter 2020-03-26 11:06:42 UTC 
State management has been reworked for 20.04 so this cannot happen anymore.
Comment 2 Erik Quaeghebeur 2020-03-26 14:21:39 UTC 
For others encountering this issue: I worked around it by copying first from one server to local storage and the from local storage to the other server.
