Error in Grass-gis 7.1. svn

[Faraslis]

I install the grass-gis 7 beta 3. But when I try to launch i receive the message

---

nul=open <os.devnull, 'w'> IOerror: [Errno 2] No such file or directory : 'nul'

---

Also for the grass-gis 7 beta 2 and beta 1 I receive the same error message

My pc is win 7 32 bit

Can you please try a fresh installer?

Replying to Faraslis:

---

nul=open <os.devnull, 'w'>
IOerror: [Errno 2] No such file or directory : 'nul'

@devs, for the record:

grep -n 'nul = open' ./lib/init/grass.py 
409:            nul = open(os.devnull, 'w')
540:            nul = open(os.devnull, 'w')
1184:    nul = open(os.devnull, 'w')

Apparently, it's possible for the service implementing the null device ('nul' pseudo-file) to be stopped or to malfunction.

The status can be checked via the control panel. Start the Device Manager (Control Panel > Hardware and Sound > Device Manager), select View > Show hidden devices, then under Non-Plug and Play Drivers, there should be an entry for "Null".

The corresponding registry key is

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Null

The Start and Type values should both be 1.

Does the problem persist with RC1?

Actually, I also experienced this bug on a win7 64bit notebook. I tried winGRASS beta3, RC1 earlier and today (23rd Feb) the stable 7.0.0 version. The 'Null' entry in Plug and Play Drivers and values in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Null were also checked and everything looked ok.
