You should see both "bitcoin" (the old 0.4) and "bitcoin-qt" (the new 0.5). @p{par} ... all of which is, I know, annoying and painful. Again, frankly, I'm more interested in spending time on the very-highest-priority issues rather than making every beta release upgrade completely smooth in all cases. @p{brk}
