Eclipse Luna on Debian Wheezy Crash

The crash is related to a version mismatch between GTK2, GTK3 and Debian's GLIBC. The relevant bug is here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=430736

To force the use of GTK2 on Eclipse Luna you can try:

$ export SWT_GTK3=0

For a more permanent solution you can set the GTK version on the eclipse.ini file:

 --launcher.GTK_version
2

This option should be inserted before the --launcher.appendVmargs option.

And now you should be able to use Eclipse Luna on Wheezy.
