Thanks for your report. Same problem when launching s-c and trying to purchase a software.

@Satriyana, only assign a bug to yourself is you actually plan to fix it.

[Vangel Ajanovski (ajanovski)]

not just for Arista, it does the same on other apps.

[Alessandro Losavio (alo21)]

Ubuntu 11.10 alpha 2 amd64

Step to reproduce it:

1) Open Ubuntu Software Center from Launcher
2) Search "skype"
3) Click on "Use this source"

The crash appears to me and the source was edded

[Alessandro Losavio (alo21)]

I had this bug when i open Ubuntu Software Center and install program too. But all work done

[James Galea (jamesgalea)]

Alpha 2:
Same as Alessandro here:
1) Open Ubuntu Software Center from Launcher
2) Search "skype"
3) Click on "Use this source"

[nakki (titibanjekistan)]

Same installing deb file from skype's site...or searching skype on sotware-center or using a bit software-center...
There are many spets to reproduce it.

[Chris Coulson (chrisccoulson)]

This is actually a bug in zeitgeist:

<chrisccoulson> hmmm, i get bug 807282 in bzr too. i wonder if it's actually a zeitgeist bug instead
<ubot2> Launchpad bug 807282 in software-center "software-center crashed with AttributeError in __getattr__(): 'Symbol' object has no attribute 'MODIFY_EVENT'" [High,Confirmed] https://launchpad.net/bugs/807282
<seif> chrisccoulson, is it and we are working on it
<seif> its actually a critical bug
<chrisccoulson> seif, awesome, thanks!

[Christopher (soft-kristal)]

It makes sense that it's due to zeitgeist, as the software center still works.

[Apport retracing service (apport)]

[Chenheting (chenheting)]

I just start trying to install some software at software-center. It pop-up to report this bug.

[Siegfried Gevatter (rainct)]

From #807076 (Zeitgeist upstream bug):

The problem is not in zeitgeist itself, but in the recent version of raptor2-utils in ubuntu oneiric.
See http://bugs.librdf.org/mantis/view.php?id=451 for the upstream bugreport.

Affected version is raptor2-utils >= 2.0.2

[Gary Lasker (gary-lasker)]

I added some code in software-center to gracefully handle the AttributeError. This will take care of the crasher in Software Center pending the real fix in Zeitgeist.

[Seif Lotfy (seif)]

The problem is not Zeitgeist itself but the upstream rdflib
