Although we can get documents from the Symbian website about the Symbian error codes and a simple explanation on how to read their errors... on Nokia phones, sometimes all I get is a cryptic MontyThread -9 error. It would be nice to have a more comprehensive explanation.
I managed to find an explanation as to what the # means, apparently it's the thread identifier (or so I read on the Symbian docs), but afaik, some phones (i can't remember any offhand) just leave it at that without any additional reporting as to why the error occured.
So I'm not sure whether to put this under Platform or Documentation feedback. I guess both, though some Nokia Documentation about the issue would be nice during the "waiting period".
