Great distro Q4os & Bookworm & KDE & PCManFM & Falkon browser.
Is this a bug ?
Several small problems with simple desktop functions.
As example:
Malformed URL trash:/ when I click the TRASH icon.

The (attached) message box titled "Error...IOExec" is written in TechLish, and may be meaningful to the programmer,,,I guess?
Click OK.

Similiar to right-click on any desktop icon and get:
Unable to create KIO worker. Unknown protocol 'tags'. Click OK.

I'm old-school MINT with XFCE habits
Any & all help is appreciated.

Make sure the /home/ user directory is not owned by root.

You might get more info from the (hidden) log file for X... /home/$USER/.xsession-errors

like this...
/home/$USER/.xsession-errors
I check/grep a few things at once,
cat /home/glenn/.xsession-errors | grep -i "(WW)\|(EE)\|(??)|error\|fail \|segfault\|fatal"

post any info here...

/home$ ls -ld
drwxr-xr-x 3 root root 4096

cat /home/$USER/.xsession-errors | grep error

I think there is an error in the path...
//hom...
If you can move //home to /home & reboot (logout & login...) & check the logs again.

Some of those QT errors happen in my system as well.

That's 64.4 GBs !!! I have two working file managers - neither will do that.
They will COPY or MOVE to another partition.
Is there a Linux re-name command ? OR a utility program ?

Aside: This appears to be the same reason I left MINT/DEBIAN. Something to do with 'psuedo file linking'.
I have a / directory containing home & other linux folders.
CD /home contains only tom.
CD /tom contains my desktop & all other user folders.
I do not understand "Invalid object path //home/tom/.config/kdedefaults/kdeglobals".
The file kdeglobals contains something about "breeze".
You know...
I don't really need to click on a TRASH folder.
Same with using the desktop as a scratch-pad. I created a desktop folder named "2do".
In fact, I'm down to Ksnip & KDEConnect as the ONLY software I use. But this week, I have a bug in Ksnip.
I wonder...

Breeze is a kde theme.

I don't understand the //home... in the error message.

rn is rename. mv is move cp to copy (all old Unix commands, I think)

but for big jobs, I would use

rsync

In particular rsync -avh /source /destination

will copy /source to /destination/source

rsync -avh /source/ will copy the contents of /source to the destination.

I'd check again before settling in for a few hours of file transfer.

It may be easier to create a new user, and move the files, IF THAT IS THE PROBLEM.

type rsync -h for more on rsync.

To GlennsPref - thanks for your help with my bugs-of-the-day !
I am now looking at the new Peppermint/Devuan distro, using my favorite XFCE/LXDE desktop.
The Q4os is a great implementation, however,the KDE software is not ready for prime time.
Today's bug; I cannot play a DVD video because I don't have access to MOUNT, KDE just popped-up saying it was mounted, and asking which player program to use. The player program starts, but the DVD is not mounted !
Oh, and the TRASH-can suddenly re-appears saying it contains 12 items. Of course I cannot see the items, because the "malformed trash-name" error mentioned earlier. Its silly for me to waste any more time with this distro.
Again - thanks for your input,,, I'm off to "Pepper/Devuan".
