--- Begin Message ---This error is due to a corrupted CSS file. Teaching dspam to handle this would require reviewing all the code for libdspam-drv-hash and fix the problem in multiple place. A better approach is to just run cssclean which has been enhanced in dspam 3.10.2+dfsg-12 to fix this kind of corruption.
