Comment 2 Tomas Hurka 2011-12-02 14:24:40 UTC 
Where are steps to reproduce it?
Comment 3 Petr Cyhelsky 2011-12-02 14:45:42 UTC 
It is thrown from compare heap dump feature, when the comparison heap dump is in wrong  format - if the same heap dump is opened through open heap dump from main menu no exception is thrown and error message is shown - maybe the behavior should be the same?
