Bug 511714

I'm not able to reproduce this on Plasma 6.5.3 or built from git-master

Steps to reproduce:
1. Create a test file and open it, close it again
2. Verify it can be reopened via Application Menu by searching for the file name
3. Delete the file on disk
4. Search for it in Application Menu

The file name is no longer found
So you still see this bug with Plasma 6.5.3 or later?

Thanks for the screen recording. That shows more clearly how to reproduce the bug. Using those steps, I can reproduce this in git-master.
Also, thanks for the logs, they are also helpful.

Dolphin - create ~/Text File.txt (in my testing, you can also create a file from command line)
Application Menu - Places - History - click on the text file
In Dolphin, Right click - delete - see warning "The trash is not available for this item's location. Permanently delete it instead?", do that. (Or, delete on command line)
After this, the file is still in Application Menu - Places - History
Clicking it produces the error

So it seems there are two interconnected things happening.
1. The file is not being removed from Places - History
2. Trying to open a deleted file should produce a more accurate and human friendly message

The bad error dialog is fixed by https://invent.kde.org/frameworks/kio/-/commit/e2ffb5199d54a27f8cdae69f6787fb2535097938.

The fact that missing files appear in the Recent Files list in the first place is, I think, another variant of bug 503840 - the database removes the file the first time it gets to that entry, but the Application Menu somehow does not detect this update while it's running. If you restart Plasma, the entry for the file will be gone.

Last time I looked at this I couldn't quite figure out what was broken, but I'll try again soon.

*** This bug has been marked as a duplicate of bug 503840 ***

I now think I know what's wrong with 503840; they're not completely unrelated but not the same issue and the fix for that one doesn't solve the deleted files sticking around.

They will be deleted if a model looks at them, but that can sometimes take a while - a plasma restart will do it, or refreshing Dolphin's Recent Files view. I'll think about whether we can do something on the kicker backend side.

(Also, the title talks about "Places - History", and that doesn't exist in Application Menu, only in Application Launcher. They use the same backend, but do things differently so what applies to one may not apply to the other, especially for Recent Files. I'll leave it here as Kicker has a similar issue, but it may need to be fixed in both).
