Another roundcube update has been released for Debian GNU/Linux 7 LTS to address a regression in the rcmail_url() function

Package : roundcube
Version : 0.7.2-9+deb7u8
Debian Bug : 843795 851214

The security update announced as DLA-613-1 caused a regression. A
missing null parameter set the $task variable in the rcmail_url()
function to a boolean value which led to service not available errors
when viewing attached images. Updated packages are now available to
correct this issue.

For Debian 7 "Wheezy", these problems have been fixed in version
0.7.2-9+deb7u8.

We recommend that you upgrade your roundcube packages.
