Folks,<br><br>I have found a very strange bug in smach. If I call sm.execute() from a function I see the following output:<br><br>Exception
 RuntimeError: &#39;maximum recursion depth exceeded while calling a Python 
object&#39; in &lt;type &#39;exceptions.AttributeError&#39;&gt; ignored<br>
<br>This message is repeated several times. If I don&#39;t call execute from
 a function (i.e. first scope in the script) then it does not happen. I 
have googled the error and it looks like it is related to redefining 
__getattr__ .<br>
<br>The strangest part is that this happens with code that used to ran 
without problems in the past. It does not happen with other state 
machine, only with this in particular. I don&#39;t remember having done any 
update to python recently.<br>
<br>Do you have any idea why this is happening and how to solve it?<br><br>Lorenzo<br clear="all"><br clear="all"><br>-- <br>Lorenzo Riano, PhD<br>Research Associate<br>Intelligent Systems Research Centre<br>University of Ulster<br>
