Description Javier Llorente 2011-11-04 22:52:35 UTC

Version:           unspecified
OS:                Linux

I have tried to create an activity on 2011-11-03-18-39-basyskom-plasma-active-devel-USB-live.iso + today's updates. Right after tapping on "Create activity", plasma-device crashes.

Reproducible: Always

Steps to Reproduce:
1. Tap on the plus button of the activity switch to create an activity
2. Typing a name for the activity
3. Choose a wallpaper
4. Tap on "Create activity"


Expected Results:  
Creating an activity shouldn't make plasma-device crash.

plasma-device crash

Comment 2 Javier Llorente 2011-11-04 23:02:28 UTC

I have also noticed that the next boot after the plasma-device crash is slower.

Comment 3 Aaron J. Seigo 2011-11-05 10:32:03 UTC

with today's updates (though, granted, on OpenSUSE) i can not reproduce and the backtrace does not look like it should be a crashing path: the signal from TaskManager is connected straight to the TaskSource object (so it can't be deleted itself at this point) and the m_tasks pointer in TaskSource is a smart pointer so is also guaranteed to exist. Task::activities() just returns a string list from the private dptr, which has a lifespan as long as the Task object itself. oddddd....

Comment 4 Javier Llorente 2011-11-07 12:16:22 UTC

I cannot reproduce it anymore with today's updates on MeeGo,

*** Bug 286012 has been marked as a duplicate of this bug. ***

Comment 7 Aaron J. Seigo 2011-11-07 16:16:48 UTC

are you sure this is fixed, as this is the same crash as in 286012 which you filed shortly after closing this report?

if you can indeed reproduce 286012 then this should be re-opened as they are the same crash.

Comment 8 Javier Llorente 2011-11-07 17:00:11 UTC

Creating an activity on 2011-11-04-22-22-basyskom-plasma-active-devel-USB-live.iso + latest updates doesn't make plasma-device crash.

Yep, I can reproduce bug #286012. (I don't have to switch to an activity to make plasma-device crash.)
Reopening bug then...

Comment 10 Javier Llorente 2011-11-23 08:41:52 UTC

Issue still reproducible on devel (it doesn't happen always though).
Verified on 2011-11-22-18-52-basyskom-plasma-active-devel-USB-live.iso

Creating an activity on 2011-11-28-09-14-basyskom-plasma-active-devel-meego-usb-live.iso makes plasma-device crash (it seems to be a different bug).

Comment 14 Javier Llorente 2011-11-30 12:27:35 UTC

Creating an activity makes plasma-device crash. The activity was created but with no wallpaper. 
This crash doesn't happen always. I got the same backtrace as the one in comment #11. Tested on 2011-11-30-09-32-basyskom-plasma-active-devel-meego-usb-live.iso

Comment 15 Javier Llorente 2011-12-06 15:52:22 UTC

I haven't been able to reproduce this crash since a few days. Tested on 2011-12-06-13-45-basyskom-plasma-active-devel-meego-usb-live.iso
