I'm following all IDE discussions on linux-ide anyway and whenever I see that I can help immediately I do it (and if I can't the issue gets its priority level according to which it will be looked at later). CC:ing me on not fully debugged problems is not helping anything. More likely that it disrupts the work-flow since people are waiting on me instead of just pushing for the solution harder...
