[Buildbot-devel] Shell command that cannot describe itself

[Almad]

Hi,
in my factory, I have a boring ShellCommand created like that:

ShellCommand(command=['sudo', 'aptitude', 'update'], **{})

However, for some reason and unlike another steps in same factory,
RemoteShellCommand is not created properly.
Any hints on that? Using 0.8.0.

Thanks,

Almad
