I am trying to upgrade the Enigma2 from 2009.10.17 and i have tried to change the enigma2 & enigma2.sh files in the \usr\bin directory only.
I tried both 2.6 and 2.7 and in both cases the error below is reported on the console.

Traceback (most recent call last):
File "/usr/lib/enigma2/python/mytest.py", line 3, in <module>
import enigma
File "/usr/lib/enigma2/python/enigma.py", line 1281, in <module>
class eGauge (eWidget):
File "/usr/lib/enigma2/python/enigma.py", line 1286, in eGauge
__swig_destroy__=_enigma.delete_eGauge
AttributeError: 'module' object has no attribute 'delete_eGauge'

If i change them back to the files that came with the image, the error is no longer there.
I note that Nab Hyperspace uses a later enigma2 version, but doesn't have a problem (i suspect because the functionality of the information page with the gauges has been removed).

any ideas?
