Are classes that include concurrent programming constructs more often associated with bug reports?

We would like to know if concurrent programming constructs are good predictors for bugs. To achieve this goal, one of the first things we'd like to know is whether classes that use concurrent programming constructs are more often associated to Issues than classes that do not use these constructs.

We also need to discover what is the role of class size on this relationship. In other words, if we normalized the classes in terms of their size, would the result still hold?
