Bug ID: 420466
Summary: Mouse and Keyboard unresponsive when deleting large
sized tree in Disk Usage
Product: krusader
Version: 2.7.2
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: disk-usage
Assignee: krusader-bugs-n...@kde.org
Reporter: griffiths_a...@icloud.com
CC: krusader-bugs-n...@kde.org
Target Milestone: ---
SUMMARY
Identified a large amount of data to delete in the Disk Usage tool. Started
delete op. I lose the use of the mouse and keyboard (with exceptions, see
below), and I cannot alt-tab to any other running window, or click on any UI
element. Other elements of the screen appear to continue working, e.g the clock
still updates. I'm not sure if the delete is even running in the background, or
why it should choose to lockup like this.
I can use the Win key to bring up the Plasma menu, but it only appears
momentarily and then disappears.
I can Ctrl-Alt-F2 to a root shell and kill krusader. Then all returns to
normal.
Deleting files via the main panel view does not suffer the same lockup, though
is sometimes quite laggy.
Smaller numbers of files seem to delete OK thru Disk Usage, but still take too
long. The above example had me trying to troubleshoot for about 15 minutes
before I gave up and rebooted, before I realised that it was Krusader actually
causing the issue, because at first I wasn't aware it was related.
The total tree size I was trying to delete is only 4.9MB
STEPS TO REPRODUCE
1. Open Disk Usage
2. Select a large tree of files to delete
3. Delete, and the whole WM locks up, from my perspective
4. Ctrl-Alt-F2 to root terminal and kill Krusader
5. All returns to normal.
OBSERVED RESULT
Lockup of mouse buttons (mouse still moves). Keyboard also unresponsive, except
as detailed above
EXPECTED RESULT
Delete should continue in the background
