My leads page gives an error 500 in both the “cards” and “table” mode when the edited contact is shown on the page (this depends on pagination).
This started after editing to add some social accounts to the lead. After saving the lead there was an error balloon in the screen saying something like “Lead with id xxx not found”.
The last few errors in the log:

After emptying the social fields in the database (the fields social\_cache, facebook and twitter) the error is gone.
It might have got something to do with the social\_cache field containing a certain character: ☀
The value was:

Hi Menolo,
You’re right. There’s an issue with storing 4 byte emoji’s in the database which causes the serialized string to become corrupt. We’ve got a fix coming in the next release.
Thanks,
Alan
