Error launching eclipse

[Javier]

When ever I start Eclipse in Ubuntu 13.10 I get this error. It may not be an important one (I still can use the IDE and is only a warning), but the problem is that Eclipse is crashing (really crashing) a short ofterwards and I can't use apport-bug because it stops on this warning instead of continue, so i get this bug report but not a bug report for the crash.

The console output:

javi@carbono:~$ apport-bug eclipse
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 14: reading configurations from ~/.fonts.conf is deprecated.
ERROR: hook /usr/share/apport/package-hooks/source_eclipse.py crashed:

During handling of the above exception, another exception occurred:
