Description Javier 2014-10-05 17:47:50 UTC 
Application: plasmashell ()

Qt Version: 5.3.0
Operating System: Linux 3.16.0-20-generic x86_64
Distribution: Ubuntu Utopic Unicorn (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
After being running for more than a couple of hour I connected a second monitor (first one being a DVI FullHD and the second one a VGA 4:3), which produces the desktop to crash several times, although it seems that now is working (I don't have yet start to work with the new set up).

Running Kubuntu Tech Preview (updated).
- Unusual behavior I noticed:
When loging after a boot, it takes up to 5 minutes from the finished load screen to the panels to appear and to the desktop being usable.

The crash can be reproduced every time.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

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

Reproducible: Always

Steps to Reproduce:
1. Connect a second screen


Actual Results:  
Plasma crashed a couple of times, although it seems it recovers.

Expected Results:  
New screen available without crashes :)

Using ubuntu PPA for kde next. Although I tagged as master the version says 5.2.0, but that wasn't an option in the dropdown while reporting the bug.

Also, but unrelated, the desktop reporting tool keep giving an error when trying to submit the bug form there with error 410.

can't reproduce.
what seems to happen is an invalid pointer in m_redundantOutputs

can output instances get deleted by themselves leaving dangling pointers in that array?

Hi,

is that question for me?

If so, please explain in more detail?, I didn't understand it
