'dict' object has no attribute 'strip'

Today I have updated my standalone windows 1.6.1 version to the newest 2.4.4. When I start it I got box with warning quoted in subject and no more action. What should I do get into my valet?

I have read "Upgrading 1 to 2" section in Electrum Wiki and understood that wallets are not compatible. That Section promises lengthy but fully automatic conversion. But in my case is only that waning message and nothing else.'

I have deleted old wallet file and made the new version recover it from seed. It seems went well. But the history list does show blanks where correspondent address supposed to be. If click details transaction  it shows all details of the transaction. Why then certain excerptions from the details not shown in the list?

Strangely history tab shows blank Description column  not only for recovered transaction but even fore newly added in this version. Everything works seems fine expect empty Description column.

How to fill it up as supposed to be?
