ADDITIONAL INFORMATION
Comment 1 Fabio 2021-10-07 08:06:35 UTC 
I verified this bug, it happens with the "icon" applet.
The applet tries to set the "filename" lineedit readonly:

https://invent.kde.org/plasma/plasma-workspace/-/blob/master/applets/icon/iconapplet.cpp#L561

this causes the lineedit to get set to an empty text:

https://invent.kde.org/frameworks/kio/-/blob/master/src/widgets/kpropertiesdialog.cpp#L1242

but because of this signal/slot connection created on the ctor, the ok button gets disabled if the lineedit is empty:

https://invent.kde.org/frameworks/kio/-/blob/master/src/widgets/kpropertiesdialog.cpp#L1032

A possible solution would be to disable the connection to the KFilePropsPlugin::nameFileChanged slot when setFileNameReadOnly() gets called.


A quick workaround for users to edit the icons: locate the relevant desktop file in ~/.local/share/plasma_icons and run eg:

kioclient5 openProperties ~/.local/share/plasma_icons/org.kde.kate.desktop

Please don't change the file name, or it will probably break.

KFilePropsPlugin: Allow to edit properties when setFileNameReadOnly is set

Don't empty the fileNameLineEdit to avoid the dialog ok button being disabled by nameFileChanged()
