[Qgis-developer] Silently fail on error or say it loud?

[Jonathan]

Hi Alessandro,
I'd suggest that failing silently is probably the worst situation for 
the user, and the code-guidelines should be updated.
The user thinks they're getting what they want and instead their request 
is being ignored. These sorts of things usually lead to users wasting 
lots of time trying to figure out what's wrong when all that needs to 
happen is to tell them (we've all had it happen to us I'm sure).

Just my 2p.
Cheers,
Jonathan
