For those who have experienced Eclipse crashing with error “C [libgobject-
1) Open System Settings
2) Select Application Appearance
3) Select GTK
4) Change the GTK2 theme to anything but oxygen-gtk
5) Start eclipse and perform the required operation which caused the crash
6) Close eclipse
7) Revert settings back to use oxygen-gtk for GTK2 apps
The crash was observed specially when trying to close the find/replace window in eclipse.
Happy coding!!!
