syslog error

[mixo]

Here is what I have
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
try:
.
.
.

except TypeError, info:
   message = "Error reading from device (%s)(%s)." %(info,buffer)
   syslog.syslog(message)
.
.
.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Now, and then I get the follwing error

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
  File "/home/mixo/prj/multimeter.8/multiMeter/src/multimeter.py", line 
220, in ?
     syslog.syslog(message)
TypeError: [priority,] message string
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Why am I getting an error, and why does it only happen sometimes?
Could it be "message" is not defined, and if it isn't, why am I
not getting the error when I try to assign it a value?

Thanks,
Mixo
P.S I am using python 1.5.2
