Eclipse Europa can't use lineedits history

Yesterday i just installed the new Eclipse version at work and suddenly i realized i could not use up/down arrows to use lineedit's history. I filed a bug against their bugzilla that got closed as duplicate of a WONTFIX/NOTOURBUG bug :-(

Actually it seems the bug is on gtk but it quite astonishes me the fact that i'm using the same gtk i was and it worked on previous version of Eclipse.

So that forces us to ask the question: As a software developer, it's better to release a product that does not work and wait for the library we use to fix itself or should we workaround the bug as much as we can?

I'm not sure which one i'd pick with my developer hat, but as a user i tell you i want things to work :D
