Actually no.

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...
