Hi, After upgrading Jessie to Stretch, using KDE, I am seeing the error message "The process for the file protocol died unexpectedly." when opening Dolphin in su mode. No files are shown. The same happens when invoking Dolphin from a root text console. This does feature in Google searches, but for dates around 2010, so unlikely to be relevant. Has anyone else here encountered this, and maybe found a work-round? Cheers, Tony
