See "Steps to Reproduce" Reproducible: Always Steps to Reproduce: 1. Open Konsole 2. Reboot (with "Restore previous session" selected) 3. Launch "konsole --new-tab" by hotkey or krunner (Alt+F2) 4. We get new Konsole window, but not a new tab Actual Results: Detect existing Konsole after reboot.
Affected Kubuntu 12.04 also.
That for reporting. I can confirm that issue. The problem is the restored konsole process has dbus address like "org.kde.konsole-<pid>", while the "--new-tab" option only works with the konsole process owning dbus address "org.kde.konsole" in current implementation.
[Developer note] The related commit is http://commits.kde.org/konsole/6b811ec2b6e4fbf459af9765c9ead506c9a0cd3c, which makes konsole avoid the "single process" model when some Qt/KDE options are given. See bug 179010 and bug 297801 for the reason behind that change. Maybe I should create a component dedicate for all those issues related with this "single process" model.
