From a quick glance I can't see anything in the stacktrace that we have control over. It's just deleting objects (on shutdown, I expect) and then referencing a deleted object.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Michał Sawicz (saviq)]

It is very likely that the attached branch will fix this.

  * Keep temporary scopes list in the Scopes object instances and make
    Scopes the partent of temp scopes instances. Temp scopes can be
    closed (and freed) using closeScope() method of the original scope,
    or by calling closeScope() method of Scopes instance. (LP: #1410337,

Querying the Error Tracker database using the bucket linked to in the description it appears that this may in fact not be fixed. This is a list of unity-scopes-shell package versions (found in Dependencies.txt) and the quantity of times an error report contains that version.

So I've been seeing this error quite a bit during my silo testing, especially from a fresh image. I am wondering if many users experience this once during the first experience. Adding to Canonical System Image for an OTA target, i figure might be too much to ask for by 6, but targeting for 7.

[Paweł Stołowski (stolowski)]

Ok, I can reproduce it with youtube scope as long as it's a temporary scope (not favorited). I've a theory about the root cause and am trying to verify that...

[Pat McGowan (pat-mcgowan)]

any updates?

[Alejandro J. Cura (alecu)]

The merge proposal is too complex to land as a bugfix, so it's been moved for OTA-8

[Launchpad Janitor (janitor)]

This bug was fixed in the package unity-scopes-shell - 0.5.5+15.10.20151019-0ubuntu3

---------------
unity-scopes-shell (0.5.5+15.10.20151019-0ubuntu3) xenial; urgency=medium

  * Hard-code Python 3.5 instead of Python 3.4.
