I have looked into this bug. Looks like it's bug also have relations to
https://bugs.eclipse.org/bugs/show_bug.cgi?id=207206#c8.
Eclipse crashes when I executing tests under linuxi686.
In error log contains some times error about gtk_win_new, some times 
contains information that i specify here later.
To reproduce this error you can use 
http://anonsvn.jboss.org/repos/jbosstools/trunk/vpe/tests/org.jboss.tools.vpe.ui.test/ 

 plugin.
