textmate and execute line

[andrea]

Hi,
I have the latest bundle for python (upgraded from svn) but I don't
understand how execute line works..

It only works if I play with arithmetic operations, something like
this works:
2*2
4


but for example trying to execute this line gives me this error, any
help?
x = 1; x + 1

Traceback (most recent call last):
  File "/tmp/temp_textmate.31Kc2h", line 19, in ?
    stdout.write(exc)
TypeError: argument 1 must be string or read-only character buffer,
not list


Thanks a lot
