Hey all,

I have a simulator(OpenRAVE) that uses qt,coin and SoQt for the GUI .On ubuntu everything works fine, but on os x I keep getting the error

Qt Code: 
  1. Qt has caught an exception thrown from an event handler. Throwing
  2. exceptions from an event handler is not supported in Qt. You must
  3. reimplement QApplication::notify() and catch all exceptions there.
  4.  
  5. terminate called without an active exceptionAbort trap: 6

Initially I thought its just on Qt 4.7, but I have also tried re-compiling the app with 4.8 and 4.6 and get the same error. If anybody has experience with this please share any means of resolving it.

Here is the full error log
