This log also didn’t explaine anything and I went to Trace:

I understood that this specific exception was generated not with my code but with CRM core operation – Sending of am email. I remain that about a year ago I faced and solved similar issue with tasks.

I hope that this topic will help other developers to solve their issue faster then I solved it.
