After update to QGIS 2.5.0-92 (OSGeo4W) I get this error:

Couldn't load plugin processing due an error when calling its initGui() method

It seems something related with the backward compatibility of models.

There are two problems in here. One, the model is not being loaded, so the backwards compatibility is not perfect. Two, there is an error in the internationalization code that Alex added during the HF. I will work on the first one. Coudl you attach the model that is causing this problem? Thanks!

Hi Victor,

I attach two models:

• with 1_1_preparacao.model, I get no error;

• with 1_preparacao.model, I get the error described.

• 7892 was configured as 1_preparacao.model
• 7891 was configured as 1_1_preparacao.model

The error with int i18n is fixed. The error of not being able to load your model is actually not a modeler error. The syntax of the raster calculator has changed, so all old models using it will break.

I will try to manually edit you model and send a corrected one back to you, since it is a very big model and i guess you do not want to create it again :-)

Hi Victor,

No, it is not necessary, I take care of it! Don't worry! These are not yet final models!

Thank you so much!

Best regards!
