When performing cutting/pasting operations in a desktop session it triggers something with kdeconnect and I see entries like this in syslog: Aug 25 11:50:48 bodhi org.kde.kdeconnect[10441]: QXcbClipboard: SelectionRequest too old Aug 25 11:52:11 bodhi org.kde.kdeconnect[10441]: message repeated 4902 times: [ QXcbClipboard: SelectionRequest too old] The desktop system essentially freezes at this point and the system must be rebooted. I solved the problem by uninstalling kdeconnect kdeconnect-plasma and rebooting. Reproducible: Always Steps to Reproduce: 1. Set up KDEConnect to connect with other devices 2. Perform copy/paste operations in a desktop session Actual Results: Session freezes. Expected Results: Session should not freeze. Copy/paste operations should not cause crash. I listed this as Grave as it kills the desktop session.
Note that this seems related to this bug: Bug 357885 - QXcbClipboard: SelectionRequest too old https://bugs.kde.org/show_bug.cgi?id=357885
Am now using Ubuntu 16.10 "Yakkety" which has kdeconnect version 0.8-0ubuntu5 and this issue no longer occurs.
I did not mark status as "resolved" since users on 16.04 LTS release may still be affected by it.
Since summer I am using openSUSE Tumbleweed (currently with kdeconnect 1.0.1, 'kdeconnect-cli' says 1.0) now and did not experience this issue during the last weeks, too.
Issue is fixed.
