Re: Crash on empty HOME var in Windows registry

So, I have installed 22.1 and tried. With no HOME env var and an 
empty (but defined) HKEY_CURRENT_USER\Software\GNU\emacs\HOME 
registry key, emacs complains "A fatal error has occurred!" and 
gives the opportunity either to abort, which stops without error, 
or to continue inside GDB, which causes a Windows "crash" 
notification since I can't prepare it with gdb -p <emacs-PID> as 
advised (because I don't have GDB installed on Windows). The 
error report is:

AppName: emacs.exe
AppVer: 22.1.0.0
ModName: ntdll.dll
ModVer: 5.1.2600.2180
Offset: 00001230

Wouldn't it be desirable to just tell the user that they have 
misconfigured their HOME or to proceed without complaining ?
