Ok, I must admit that I forgot about the whole thing, so called Twitapocalypse. According to what was predicted before and happened a few hours ago, qTwitter 0.7.0 is not updating timelines correctly. A small patch fixed this unwelcome behavior and it was instantly applied, making qTwitter 0.7.1. So please update your app to the newest version that deals with huge IDs of Twitter statuses. Get it, as you always do, from qt-apps.org. Apart from the fix, in 0.7.1 release you’ll get support for digg.com URL shortening service and some look and feel corrections concerning the user info popup dialogs. Happy tweeting :)
