Bug 398300

Application: plasmashell (5.13.4)
 (Compiled from sources)
Qt Version: 5.11.1
Frameworks Version: 5.49.0
Operating System: Linux 4.18.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.6"

-- Information about the crash:
- What I was doing when the application crashed:
Successfuly decompressed another Windows created zip file to a subfolder. Opened a zip file from USB Storage (around 1.6 GB, 182 files). Selected all files (Ctrl + a) and right clicked and Copy and tried to paste to a folder under of my home folder. It shown an error message that the file from previously uncompressed file does not exist. Closed the Dolpin (Ark) window with the previous zip file content and tried to paste again. The same error message. Closed the zip file, opened it again, selected all, copy, paste and the same error message about non-existening file in the previous archive file. Repeated twice or three times and after last try got this back trace.

- Unusual behavior I noticed:

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
