No, it's not. The globals() (i.e., the "context") are of the imported  
module itself, not of the caller. The error probably lies on how that  
template attribute is converted into a full path; post that code.
As an example, this is a rather safe way, even if the program uses  
os.chdir():

basepath = os.path.abspath(os.path.dirname(__file__))

class ObjectWidget:
     template = "templates/objectwidget.pt"

     def open(self):
         fn = os.path.join(basepath, template)
         print fn
