Eclipse crashes when content assistance popup is displayed

After upgrading to ubuntu 14.04 Eclipse is crashing just right after Content Assist popup is displayed.

When launching eclipse from console I get this:
No bp log location saved, using default.
[000:000] Browser XEmbed support present: 1
[000:000] Browser toolkit is Gtk2.
[000:000] Using Gtk2 toolkit

Searching for similar errors I found this bug - https://bugs.eclipse.org/bugs/show_bug.cgi?id=334466

I've removed these packages from my system and it did help:
libwebkitgtk-1.0-0
libwebkitgtk-1.0-common
python-webkit
webkit-image-gtk

Eclipse doesn't crash now, so we can consider it as a workaround. However now in Content Assist I see style formatting text, e.g.:

/* Font definitions */ html { font-family: 'Ubuntu',sans-serif;
 font-size: 11pt; font-style: normal; font-weight: normal; }
 body, h1, h2, h3, h4, h5, h6, p, table, td, caption, th, ul, ol, dl,
