Plasma widgets such as yAWP and the CPU load monitor appeared to be frozen - no updates, no animations

kactivitymanagerd (1.0) on KDE Platform 4.7.97 (4.8 RC2 (4.7.97) using Qt 4.7.4

- What I was doing when the application crashed:
→ Logged in to KDE
→ Rightclicked on the 'Instant Messaging Presence' applet of KDE Telepathy in the systray
→ Selected 'Online'
→ Activity Manager crashed

I don't think the crash was related to the status change of KDE Telepathy, but as I'm not sure I've added it to the information. I think the crash was simply related to the KDE startup such as the other reported crashes before.

Comment 9 Elias Probst 2012-01-13 11:43:41 UTC
I'm now able to crash it nearly everytime when doing this:
→ Log in to KDE
→ Start switching between activities as soon as possible
→ Crash

It looks like there's some kind of a race condition. plasma-desktop requests an activity switch to be done, while the activity manager wasn't able yet to load the activites from Nepomuk.
Comment 10 Janek Bevendorff 2012-01-29 11:16:26 UTC
I have similar problems, but I don't even need to switch activities manually. Each time I start KDE, I just have to wait a few seconds and then I get the message

"We are sorry, KDE Activity Manager close unexpectedly.
[...]
Details: Executable: kactivitymanagerd PID: 4627 Signal: Segmentation fault (11)"

It doesn't seem to affect anything. When I close the dialog, activities still work (although I don't use them), but this dialog is kinda annoying.

System: Gentoo Linux AMD64, KDE 4.8.0 (didn't happen with 4.7.4).

I had the same problem on my Fedora box, but not on Arch. On Fedora, I could use the ugly workaround of throwing away all nepomuk data and start all over in that department. After that, no crashes on Fedora, and a working activity manager.
 This leads me to the suggestion that it is not so much a plasma bug, but probably a soprano version issue.

I don't get this bug anymore. After the install of 4.8 RC, I noticed a new activity was created named 'New Activity' (if I remember right). So, I deleted the new activity and also others that I don't use, and I'm left with only the 'Desktop' activity. Since then, I haven't had the crash anymore.

Comment 15 Randy Andy 2012-01-30 16:20:49 UTC
I have similar problems, but I don't even need to switch activities manually.
Each time I start KDE, I just have to wait a few seconds and then I get the
message. Especially when kwallet Password request comes up, and wasn't entered fast enough. Then four more password windows comes up, i guess from kmail. That's the moment when the crash happens.

System: Gentoo Linux AMD64, KDE 4.8.0 (didn't happen with 4.7.4).

Debug Info see as attached file.

Comment 23 Rolf Eike Beer 2012-02-05 20:56:36 UTC
For me it looks like you are happy when it crashes. If it does not it will not respond to dbus calls, leading to plasma workspace being extremely laggy (i.e. will take like a minute for anything to happen on click). Killing the activity manager daemon then will make things behave properly again.

I see this now every time I log in. I don't ever use activities but when I checked, I found they had multiplied enormously, with many having identical names (but not identical icons). Some are disabled, some enabled, some active, some can be configured, some not. I deleted a number with spherical icons as opposed to meaningful icons. I've not got one spherical one left which seems to be default so I guess I can't get rid of it and 3 disabled ones with meaningful icons (search, desktop icons, photos). I've never been sure what these were for. I think this means I've lost the original main activity but I'm not sure.

Knock on wood - since the KDE 4.8.2 update on Kubuntu 12.04 I haven't seen this bug for the last 3 reboots.
Comment 58 Ivan Čukić 2012-04-05 06:24:46 UTC
You shouldn't see this bug in 4.8.2 (and later) simply because the nepomuk plugin is not used anymore - so there is no mutithreaded nepomuk access anymore.

KAMD still saves some data into nepomuk, but not as much as before.

That is the reason I haven't closed this report - the multithreaded nepomuk access issue is still here, just kamd is not triggering it anymore.

In order to reproduce, kamd needs to be build with KACTIVITIES_BUILD_NEPOMUK_PLUGIN option activated (and the sqlite plugin needs to be disabled when starting kamd)

New crash information added by DrKonqi

kactivitymanagerd (1.0) on KDE Platform 4.8.1 (4.8.1) using Qt 4.8.0

This crash occurs when logging in to KDE 4 (every time)
It might be linked to another segfault with Kmix, which comes first and is raised as a duplicate of this lead ticket https://bugs.kde.org/show_bug.cgi?id=290742

Hello,

is there a temporary solution available?
I am using openSuse 64 bit current with Tumbleweed.
I cannot send emails via kmail and furthermore I cannot access my emails
stored in kmail.
For the permanent solution: How long will it take to make 4.8.2 available
in the Tumbleweed repo?
Thanks
Stefan

You can try the following (but I don't know whether it will work) - open .kde/share/config/activitymanager-pluginsrc and add the following to the [Global] section:

disabledPlugins=activitymanager_plugin_nepomuk

So the file would look something like this (and restart KAMD)
[Global]                                                                                                                                      disabledPlugins=activitymanager_plugin_nepomuk

Thanks,

I do not have this file.
I checked .kde and .kde4.
Is there an easy way to create this file?
Something to consider like header or format to save the file?
An example is appreciated ;-)

Here you go:

Comment 65 stefan fischer 2012-04-12 14:21:26 UTC
Thanks for your effort but this solution does not work.
Is it possible to add a stable kde repo to my above mentioned environment?
Up to now I am afraid that adding an additonal repo can cause an instable
system.
By accident I renamed my activitymanagerrc file and now all desktop icons
are gone.
Renaming this file back to its original name does not show any success.
I think I should stop here playing around with my productive environment.

This is now marked RESOLVED UPSTREAM.  Is there some explanation of what the upstream problem is, and which ticket is attached to it?  I don't see anything indicating what is believed to be going on.

I logged into the desktop.

It waits until I have launched an application.

Comment 84 Randy Andy 2012-07-19 17:36:46 UTC
Every time i logged on, kactivitimanager crashed sooner or later. Also Kmail crashes very often while using.
Virtuoso-t process consumes about 30% of my Quad-Core CPU load, although strigi doesn't index anything.
I also noticed a strong delay when logging in, until kmix, klipper and strigi symbols came up.

Some of my interestingly findings:
After logging into the desktop, before the activitymangerd crashes, the akonadi test results was fine, after the crash the following fault was in:
Nepomuk search service not registered at D-Bus.
If the crash happens very early after log in, the kmix, klipper and strigi symbols doesn't came up at all sometimes.

I tried every forum and bug report hints i could find, nothing works until...
I deleted the following directory ~/.kde4/share/apps/nepomuk (while not logged into kde of course).

Logging in is pretty fast now, kmail much more responsive than before, and kactivitymanagerd doesn't crash once since this.
Akonadi's error log is clean now and hopefully stays so. 

So that's the solution for me and also for another guy who takes this advice, I gave to him in the gentoo forum. Eventually this is the reason for some other bugs like the virtuoso CPU consumption Bug 293641 and one reason for kmail crashes too - hopefully.

So give it a try, but beware of the fact that if you've done some tagging of indexed files, this would be lost in this case and a new re-indexing of your hard drive is necessary!
Do a backup before or something else to save your work, if its important for you.

Much success, Andy.
Comment 85 Janek Bevendorff 2012-07-19 18:38:05 UTC
You should really address only one issue per bug report.
The virtuoso problems you describe are well known, but you shouldn't mix everything together. ;-)

Ok Janek,
