Hmm, I though we decided that some hint to pretty-printers is desirable.
Anyway, let me repeat my point -- the descriptive string is rather long,
so might not fit in variables window. Further, a frontend typically
has some way to display variable type already, so "std::vector" part 
of the string is not helping either. So, I'd much rather have {...} for
all composite types in MI.

I don't know either. The current behaviour *feels* strange, but then my
WIP patch for kdevelop does not use this field at all, for incremental
fetches. Maybe we can leave it as is, for now.

Any comment on the crash?
