What is the exact SWT version used? What distro? Which Gtk version?
Comment 2 Thomas Singer CLA 2014-07-09 15:03:46 EDT 
SWT 4.3.1, more information we don't have - it's from an automated exception reporter without direct end user email contact

It would be very hard for me to debug this without a pure swt snippet that reproduces the problem (a reproducer step-by-step" might give it a chance).
Comment 4 Thomas Singer CLA 2014-07-15 00:54:38 EDT 
Maybe you could add further checks as a first step?
