Problems with regular expressions

[Carlos Luis Pérez Alonso]

I have the next piece of code:
 
------------------------------------------------------------------------
 if re.search('^(taskid|bugid):\\d+',logMessage):
        return 0     
else:
        sys.stderr.write("El comentario tiene que contener el taskid:#### o el bugid:####")        
        return 1
-------------------------------------------------------------------------
 
The regular exprexión is "^(taskid|bugid):\\d+"
 
Mi problem is that if logMessage == "taskid:234" the regular expression matched teorically, but the result is always "None" and the function returns 1.
 
¿Does anybody has an idea of what is happening here?
 
Thanks
