Thanks for the answer. I forwarded this along to them.

(I also confirmed that this problem only exists in 2.11.0 -- 2.10.X is safe from it).

Actually the mi support for listing context was added in 2.11 [1]. This seems to be tracecompass expecting regular text output despite it is passing the "--mi xml"
