[RCU] Recieved email (content-type="multipart/alternative") not being rendered (I can't see images)

Hi,

I have installed roundcubemail-0.3-stable in a LAMP platform.

When I received an email with an inline png image (and content-type="multipart/alternative"), roundcube doesn't display it. Mozilla Thunderbird for example display the image correctly.

When I forward or 'edit as new' the message, the image is showed without any problem. It seems that there was a solved ticket with this problem, but I don't know how to fix it.

I rescue an old roundcube installation (roundcubemail-0.1) and the same e-mails that didn't display the stable roundcube0.3 works fine here. Maybe this could help.

Thanks in advance for your help.
