The roundcube webmail client was updated to roundcube-0.1_rc2 on 20/10, containing bugfixes and improvements. Renaming the ebuild that currently is in the webapps experimental overlay works fine for me on x86. No obvious bugs as far as I can see ... (and now with a preview pane although not yet official). Please bump to this new version when you can find the time.
