Summary: Indexing a struct type in the Taskbrowser triggers an
assertion

If I create a variable in the Taskbrowser based on StructTypeInfo and try to
index it (which it does not support) an assertion is triggered:

Deployer [S]> var ConnPolicy cp
= {type = 0, init = false, lock_policy = 2, pull = false, size = 0, transport
= 0, data_size = 0, name_id = }

Deployer [S]> cp[0]

RTT::base::DataSourceBase::shared_ptr RTT::types::StructTypeInfo<T,
has_ostream>::getMember(RTT::base::DataSourceBase::shared_ptr,
RTT::base::DataSourceBase::shared_ptr) const [with T = RTT::ConnPolicy, bool
has_ostream = false, RTT::base::DataSourceBase::shared_ptr =
boost::intrusive_ptr<RTT::base::DataSourceBase>]: Assertion `false && "You're

rttlua does not suffer from the assertion problem and gives an error as
expected:

> rtt
rtt. rttlib.
> cp = rtt.Variable("ConnPolicy")
> =cp
{data_size=0,type="DATA",name_id="",init=false,pull=false,transport="default",lock_policy="LOCK_FREE",size=0}
> =cp[0]
