Missing dependency on syslinux-themes-debian

I had previously removed package "syslinux-themes-debian" because I had nothing installed that depended on it. Then I tried to install lowlatency kernel:

$ sudo aptitude install linux-lowlatency
The following NEW packages will be installed:
  linux-headers-3.2.0-48-lowlatency{a} linux-headers-lowlatency
  linux-image-3.2.0-48-lowlatency linux-image-lowlatency linux-lowlatency
  rtirq-init{a}
0 packages upgraded, 6 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B/39,5 MB of archives. After unpacking 160 MB will be used.
Do you want to continue? [Y/n/?]

The workaround is to install package syslinux-themes-debian manually, so I guess linux-lowlatency should add that as a real dependency.
