Comment 1 Germano Massullo (Thetra) 2017-06-21 18:06:07 UTC 
I edited bugreport title because it happens also on non FTP folders
Comment 2 Julian Steinmann 2018-05-20 15:18:48 UTC 
Does this crash still happen with a newer version of Dolphin (e.g. 17.12.3 or 18.04)?

I cannot reproduce on dolphin-17.12
Comment 4 Julian Steinmann 2018-05-20 15:23:38 UTC 
Great, thanks for the quick response :)
