Sentry Crash Report:

Description Edward Donovan 2013-12-29 21:47:24 UTC 
Application: plasma-desktop (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-15-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

I was trying to learn and use the Activities system for the first time.  The crash came shortly after creating the third new activity.  It may have been while trying to switch a window to the new activity, from the title bar context menu, but I can't remember exactly.  It could certainly be a duplicate, but the list of possible duplicates was overwhelming; too long to possibly check.  For the ones I did look at that seemed somewhat similar, it was too hard to determine which, if any, might be right.

I don't think I was doing much more than putting the Activity system through its basic paces. :(

Thank you.
