Comment 1 David Edmundson 2015-01-28 17:39:49 UTC

>I was renaming an application launcher (changing title) in the desktop window with applications.

I don't understand what you mean by this.

Comment 2 Sergei S. Rublёv 2015-01-28 18:06:00 UTC

Created attachment 90757 [details]
crash file

Sorry, I was trying to report many Plasma crashes (as KDE proposed to me), but bug report tool couldn't publish them. This report happened to be the 1st one to be published. Here are steps I made to reproduce:

1. There is a "folder" widget on the desktop with shortcut icons and files

2. I have added a "Link to application" to it

3. I wanted to rename this "Link to application" and I right-click on it and go to "Properties"

4. In "General" tab I enter the new title, click OK

5. I get "Error — Plasma" window with message "The process for the desktop protocol died unexpectedly."

6. I click "OK" and experience the crash of "plasmashell", which immediately restarts and leaves bug report window.

I have attached the generated backtrace file.

Comment 3 David Edmundson 2015-01-28 23:17:37 UTC

OK, I can confirm I'm getting that error.
I'm not seeing Plasma crash as yet.

Comment 4 Eike Hein 2015-01-28 23:20:40 UTC

Hm, I'm not getting that error. What's your versions of kio and kio-extras?

Comment 5 Eike Hein 2015-01-28 23:22:43 UTC

Scratch that, I do get the error, but only when Folder is used as a widget, not in the desktop containment case (weird and interesting). I'll investigate tomorrow.

Comment 6 Sergei S. Rublёv 2015-01-29 09:25:24 UTC

My yum package manager doesn't list a package named kio. It does list kio-extras and its version is 5.1.95-1.beta.fc21. There is also kf5-kio-core.x86_64 and its version is 5.6.0-1.fc21.

Comment 10 Eike Hein 2015-01-30 18:53:53 UTC

David,

this kio_desktop crash happens because it's a QCoreApplication but QClipboard needs a QGuiApplication to access QPlatformIntegration::clipboard(). We have other kioslaves that are QGuiApps for similar reasons (e.g. the thumbnail slave in kio-extras). Do you agree this is an appropriate way to go?

Comment 11 Eike Hein 2015-02-02 16:21:31 UTC

Git commit f57bf64326f865660b0d24392037157413dc995a by Eike Hein.
Committed on 02/02/2015 at 15:50.
Pushed by gerrit into branch 'master'.

Check we're a QGuiApp before using ClipboardUpdater.

Matches other callsites in the file and prevents a known crash
in kio_desktop.
