Hi All,
As soon as statistics are enabled, or infact that are any statics for
the repo I get the above error. The console output is:

As soon as the statistics are reset everything works fine. If they are
enable again then the same error occurs.
This is on a installation that has jsut been upgraded to RhodeCode
1.2.3.

I hate to top post.
Just did search on this group to see anyone else has had this error.
I came across this:

However I don't know how to implement this.

Can anyone help?

I know few users told me that there are problem with JSON serialization, would be awsome if i would know why, and on what it crashes.

Could You send me somehow a repository that's causing problems ?

Thanks

You can see that I enable the statics and then it falls over.

Tried that one on windows and it works fine also. Without a example i can reproduce cannot fix this, sorry

 I think i might know what the problem is. Can you update to the latest stable branch and see if it's fixed there ?
You can do that with this command

pip install --upgrade https://secure.rhodecode.org/rhodecode/archive/default.zip

Hmm there was an issue with this, and i think i solved it, can you provide a troublesome repository i could reproduce this issue ?
