Hello.
Couple weeks or even maybe months back I started to experience strange behaviour. When new message comes it's properly indicated by an icon in system tray. When there are more unread messages and I open the first one, it has a whole unread message from second conversation - including nickname. When I close and open "corrupted" conversation proper message is shown and everything is fine. See attached screenshot for an example.
