software-center crashed with TypeError in _check_members(): Collection contains member of invalid type <type 'list'>. Expected <class 'zeitgeist.datamodel.Event'>

This crash has the same stack trace characteristics as bug #714035. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

Hi apopovas! Thanks for your bug report. Could you please update your system to the latest version of software-center using update-manager and see if this is still an issue? This issue should namely be resolved from s-c 3.1.23.3 onwards. Your bug report however would indicate that you are using s-c 3.1.24.1 - so this doesn't quite tally. Thanks again for your help.

So this is the weird part - this problem is very percistent - I
constantly update (just did that now), it still haven't disappear. This
is the message while trying to launch software center from terminal:

After trying to change permissions in .cashe/software-center manually,
software center opens, but in terminal it outputs:
