[Qgis-developer] QGIS crashes when loading Traits from Python console. [Was: QGIS Processing Framework]

[Joona Lehtomäki]

Hi,

I can confirm the crash on Fedora 15, QGIS 1.6 and ETS 3.5. However, 
after installing the fresh ETS 4.0 from Github 
(http://code.enthought.com/source/) I can import traits.api (namespace 
'enthought' has been removed in 4.0) through QGIS Python console. Same 
applies to openSUSE 11.4 (64-bit) with QGIS 1.7. Official RPMs seem to 
be available at least for openSUSE.

Cheers,

Joona
