Bug ID: 403477
Summary: Dolphin Hangs and is Unkillble when opening folders
Product: dolphin
Version: 18.04.3
Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: accounts+...@moochermedia.co
CC: elvis.angelac...@kde.org
Target Milestone: ---
SUMMARY
Dolphin will hang when opening certain directories. there isn't any consistency
to when this happens. When it does hang it cannot be killed even sending a
SIGKILL has no effect. The Dolphin window will stay open, but all the colors
will be greyed out, and the window can still be moved around, just not
interacted with.
Side Note: There is no way to easily format text/code or insert image son this
bugtracker??
STEPS TO REPRODUCE
I cannot reliably reproduce, it happens at random.
OBSERVED RESULT
Dolphin does not open folder and instead hangs.
EXPECTED RESULT
Dolphin opens folder.
