Help with crash logs

Hi all,

 

In one of our customer’s machines, whenever he quits the application, it appears to quit normally but after quitting, Mac OS reports that the Application crashed followed by the following crash log which seems to point somewhere in the library cleanup and unloader code. My guess is that one of the libraries which spawns thread 2 at the start of the execution but even at quit this thread 2 doesn’t seem to quit maybe this is the case.

 

 I am really stuck here and I have no idea what is happening, any pointers would be really appreciated.

 

P.S. If this is not the right forum to ask this question, please point out the same.
