This bug was introduced after commit # 24102 (BGE: when letterbox is enabled use the camera framing as a clipping area) reported in IRC by Pete Carss (domejunky)
*) an extra stub fix for recent commit. By the way: we want to have blenderplayer running in blender 2.5 beta0. Therefore if you are doing big changes in the last minutes (Friday, Saturday??) It would help a lot if you could enable blenderplayer in your builds. links problems are really easy to fix)
**) an typo I spotted in recent mesh dynamic load in bge.
