[QGIS-Developer] Custom processing script instabilities

[Luigi Pirelli]

hard to say something without reading the code... btw generally you do not
have to interact with main GUi from a processing alg that by default run in
a separated thread => this can cause crash if you do not use standard
processing libs (e.g. feedback) to send message to the user.
No idea if this could be the source of the problem., IMHO sharing the code
would help and also help to verify if it can be replicable.
