PlaySMS mixed incoming messages

PlaySMS mixing incoming SMS.

for the demonstration, I sent several SMS with the same text: тест1 тест2 тест3
in russian language.
To the received messages are added tails from old messages: только Во

I’ve found problem - It’s in gammu-smsd!


Care to tell us the solution? I saw another question about this too but no solution yet. Thx.
