I just removed the Hebrew translation of plasma from the 4.2 branch, which means only plasma will not be translated to Hebrew. The reason, is that QGraphicsScene does not support RTL interfaces in Qt 4.4, and it's still not sure if KDE 4.2 does support Qt 4.5. Even if it does, it's still not tested.
If KDE 4.2 will work with Qt 4.5, the translation will get pulled from trunk again.
I hope that no more files need to be remove, otherwise I am afraid of going bellow 85% and in theory Hebrew will not be a supported language.
