The reporter indicates this bug may be a duplicate of or related to bug 334674.

Possible duplicates by query: bug 336882, bug 334846, bug 334674.

Report to https://bugs.kde.org/

Reproducible: Didn't try

Steps to Reproduce:
1. Reboot
2. KDE Login

Actual Results:  
Pop-up appears immediately, indicating that Plasma has crashed.
Then Plasma is apparently restarted, and everything looks "normal".

Expected Results:  
It should not crash of course ...

Possibly related to recent updates
- kactivities* 4.13.3-5.fc20
- kde-workspace 4.11.11-4.fc20
- kde* (several kde apps)
- plasma-scriptengine-python 4.11.11-4.fc20
  Make kactivities dependencies less strict, so that only kde-workspace
  depends on it.  This will provide an easier upgrade path to Plasma 5.
?

Same thing happened to me.

By the way the crash handler does not work. It said I had to login to the bug reporting system first despite I had already entered my login details. I logged into the web site manually and hit the 'retry' button but that did not work either.

Application: plasma-desktop (4.11.12)
KDE Platform Version: 4.14.1
Qt Version: 4.8.6
Operating System: Linux 3.16.0-28-generic x86_64
Distribution: Ubuntu 14.10

-- Information about the crash:
- What I was doing when the application crashed:
logged on for the first time after a fresh boot.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
