The terms and conditions of the bond swap Greece agreed to before getting another handout constitutes a theoretical default - but not a technical default.
That's not funny to CDS holders.
Greece hasn't defaulted (so far), but some of the buyers of credit default swaps, basically insurance policies that pay off if there is a default, claim the terms and conditions of the bond swap constitutes a "credit event" or default.
If it is, they want to get paid.
