Bug ID: 420542
Summary: Djvucreator.cpp crashes when trying to make a fork on
line 72
Product: kio-extras
Version: unspecified
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: Thumbnails and previews
Assignee: plasma-b...@kde.org
Reporter: mirchevmartin2...@gmail.com
Target Milestone: ---
SUMMARY
When opening a file with .djvu files, it does not generate a thumbnail and
constantly sends a notification that kdeinit5 has crashed. I have currently
traced it down to line 72, but I have no idea what is the problem and why a
fork is unavailable.
STEPS TO REPRODUCE
1. Make a folder with atleast 1 .djvu file
2. Wait for it to generate a thumbnail for Dolphin
3.
OBSERVED RESULT
A notification is sent for a crash.
EXPECTED RESULT
A thumbnail for a .djvu file is shown.
