I run the following script: -- from subprocess import * Popen("ls -l") -- (yeah, I have ls.exe on Windows)
Under Python 2.4.2, this simply dumped the results of ls.exe to the terminal--sorry, to the "command shell". Under Python 2.5, both beta 1 and beta 2, it dumps the results to the command shell, but also prints this: Exception exceptions.AttributeError: "'NoneType' object has no attribute 'append'" in <bound method Popen._del_ of_ _<subprocess.Popen object at 0x00C04EB0>> ignored Calling Popen() with a stdout = subprocess.PIPE does not throw this exception.
I've asked Larry to raise this on SourceForge, but with the SF email problems I thought I'd better forward it here.
Looks like there's a bug in Popen.del in 2.5. I'm not in a position to have a look right now.
