Comment 23 for bug 1448102

Sorry, it's stranger than that..

plasmashell crashes on boot.
1) rm .cache
2) kbuildsycoca5
3) plasmashell
crash just like on boot
4) rm .cache
5) plasmashell (from console)

* Black screen, but no crash

6) ctrl+c in console to stop plasma
7) kbuildsyoca5
8) plsamashell

* At this point I have a desktop background but no menu bar. (repeatable)

9) rightclick > add panel > default panel

* crash

10) rm .cache
11) plsamashell
12) ctrl + c
13) kbuildsyoca5
14) plasmashell
15) right click add empty panel.

* Yeah, no crash!!!
* Boo, no items in panel..

16) add clock to panel (no crash)
17) add volume control to panel (no crash)
18) add application launcher (no crash)
19) add Icon only task manager (no crash)

.. Okay, I have enough in my task bar to start working again.. If I ever figure out what item in the plasmashell -> default panel was crashing I'll let you know.

(I was getting it to crash in 15.04 after the computer lost power, I upgraded to 15.10 and it still crashed.. Lots of variables, but it appears this issue might span releases)
