Hi Alexander,
for users who want use those algs this is too restrictive, Could we find a way to check if 3rd party modules are installed in system ?
it would be nice to warn the user that in sextante are available more algs but they requires the following 3rd party modules.....

Something like this:

try:
  import third_party_module
  third_party_module_loaded = True
except ImportError:
  third_party_module_loaded = False 

if third_party_module_loaded:
  load_algs

I would use those algs ! Thanks !

This is temporary solution, currently SEXTANTE won't load for many users without scipy and matplotlib installed. I agree that run-time check for dependencies is much better and will try to implement it.

aha... this was helpful in figuring out how to stop runtime sextante related errors during qgis startup (Fedora 18). now qgis is setup properly on this machine.
