blank messages from 1.1.1970?

[mida]

i used dbchecker in aggressive mode and get many orange and red messages. after this i check my history with one contact and found this, see my screenshot.
i deactivate this account at the moment, thats why see unbekannter Kontakt (unknown contact).

i used global historysearch with filter only from 1.1.1970 to year 2000 but it doesnt find a message
how i can use history search to find all blank messages from 1.1.1970 to can delete?

That's probably indicate database corruption. The "messages" you see aren't actually have a date, these may not me actual messages at all.
If you have a copy of the database before and after this conversion, developers would be interested to see it, I presume.

this is no problem for me, my main computer should work in a few days, than export my new history from this backup db to my work computer and can delete this.
and my question is, is there a way to find all others blank messages instead of manually?

mida, as AnrDaemon mentioned, I think these messages aren't empty - they're corrupted. But anyway I'm not sure History++ support searching blank messages (if they aren't corrupted)...

[mida]

yes i know thats corrupted but it looks how blank messages, thats why i written it.
i think i cant do with there corrupt messages but its not tragic
