I was able to reproduce this, intermittently
See https://bugs.kde.org/show_bug.cgi?id=418074 

There are a number of bugs related to crashes in kdeconnect if the user atteempts to transfer multiple files, or a large file, from a phone to Plasma. I'm not sure they are all duplicates. I'm listing them here so that someone more knowledgeable can more easily take a look at them as a group.
