Can you run

ls - ~/.cache

and tell me if any files are owned by root?

Every file in .cache is mine (no root owned files).

Comment 3 Kenny D 2015-10-16 09:42:18 UTC 
Plasma also crashes for me any time i'm copying either a lot of files or a largeish file using dolphin
Comment 4 David Edmundson 2016-11-04 22:58:11 UTC 
This is against an old version of Qt/Plasma and there has been no update or newer duplicates.

Hopefully that implies this has been fixed in the many developments that have happened in Plasma and our supporting libraries. If it still occurs please open a new bug report with a more recent backtrace.
