[SOLVED] Python 2.7 - platform.system(), Error10 - no child processes

Hi there,

I have a problem with my python2 and this simple script:

#/home/peta/simple.py
import platform
print platform.system()

When I run it from urxvt with "python2 /home/peta/simple.py", everything is just fine. But when I start it either from dmenu_run or gmrun, I'll get the following error:

Traceback (most recent call last):
  File "/home/peta/simple.py", line 3, in <module>
    sysname = platform.system()
  File "/usr/lib/python2.7/platform.py", line 1310, in system
    return uname()[0]
  File "/usr/lib/python2.7/platform.py", line 1277, in uname
    processor = _syscmd_uname('-p','')
  File "/usr/lib/python2.7/platform.py", line 1012, in _syscmd_uname
    rc = f.close()
IOError: [Errno 10] No child processes

Initially, I was trying to blame it on dmenu_run (https://bbs.archlinux.org/viewtopic.php … 0#p1332000), but it seems to be a problem with my python or system.

My dmenu_run is started from 2bwm WM with execvp, my .xinitrc ends like this:

2bwm &
exec urxvt

Am I missing something? Any ideas are welcome.

So, I kind of have a solution. I'm not sure, if I should blame 2bwm or python or threads or children... I guess the problem is caused by interthread communication, or something similar to it (I believe).

Anyway, my solution is to use xbindings for starting dmenu_run instead of starting it with shortcut defined in my wm.
