conffile changes in SRUs

Bug 1014732 in mysql-5.5 (Ubuntu Precise) "log_error not set in my.cnf,
errors not written anywhere" [High,Triaged]
https://launchpad.net/bugs/1014732

I've had this sponsored twice but been trumped by security twice before
it got looked at by an SRU team member.

But there seems to be some doubt on whether SRUs can change conffiles,
so I think it would be helpful to clarify this here first.

Are conffile changes allowed in SRUs? And if not, how should I approach
fixing this issue?

Thanks,

Robie
