Yup, and what I used to do in a case like this was to insert a printf
statement in that constructor of SharedString (the one that only takes
OUString) to see if anybody is calling it.  If somebody is calling it,
set a break point there and you'll find the culprit.

One likely scenario is where someone is passing a OUString value to a
function that expects a SharedString.
