2.5.1 Insert into post not working (it did before)

Im very concerned, i didn’t had all the issues everyone was claimed to have in the 2.5 version, but now that i did the upgrade to 2.5.1 the “insert into gallery” feature gets stuck, and doesnt insert anything… i dont even have plugins installed, except for “QuickPost-it”, but i disable it, and still not working…

I reinstalled wordpress.. still not working, so it’s not my fault, you guys changed something, so the real question is: when are you gonna fix this? maybe 2.5.1 came out too soon as 2.5??

This is annoying
