Dia failed with exception= 'module' object has no attribute 'Popen4'

[anonymous]

i'm using

• trac 10.3 on
• win with
• python 2.2 and
• dia 0.96

i added dia to the win environment vars and changed the line in the DiaView.py file

 dia -l --filter=png --export=test.png test.dia 

the error i get is:

Dia failed with exception= 'module' object has no attribute 'Popen4'

when i run the command from the win-command line dia works well and i'll get the following output (since i do not use X)

could not import gtkcons.py
test.dia -> test.png
