Application Error WINSETUP caused a General Protection Fault in module USER.EXE at 0001:40B6. And then: Standard Mode: Bad Fault in MS-DOS Extender.

I tested with QEMU from Ubuntu 14.04 and 16.04 and recent GIT (ef8757f1fe8095a256ee617e4dbac69d3b33ae94). Windows 3.1 has the same problem, but the errors are slightly different: Application Error WINSETUP caused a General Protection Fault in module 0C77:7011WINSETUP will close. Application Error WINSETUP caused a General Protection Fault in module KRNL386.EXE at 0001:9F03. The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could 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 state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has be [Expired for QEMU because there has been no activity for 60 days.]
