Eclipse crashes while showing code completition (libwebkitgtk)

[Apparently the workaround described here: https://bugs.launchpad.net/ubuntu/+source/eclipse/+bug/905814, stills works. But that does not mean that the bug should not be fixed]

This is happening on saucy.
I open Eclipse, type a few characters and press Ctrl+Space to trigger code completition, inmediatly after the dialog with the alternativees I choose one (the first because is the one I want) by pressing enter => Eclipse crashes. According to the console output the problem is outside the Java JVM and in the native library libwebkitgtk.

Console output (two runs):

javi@carbono:~$ eclipse
