For this we need to know which bugs are still valid and which co= uld be closed already. Thus we are setting older bugs to "Incomplete" now. If you still think this bug report here is valid, then please switch the st= ate back to "New" within the next 60 days, otherwise this report will be ma= rked as "Expired". Or mark it as "Fix Released" if the problem has been sol= ved with a newer version of QEMU already.
