Package: request-tracker4 Version: 4.2.12-6 Severity: normal As discussed on the #rt IRC channel several months ago, the Debian packages set WebBaseURL from debconf, when upstream says that this should nearly never be set directly.
I suspect that this isn't strictly required, but may be wise purely so that when people ask for help the configuration is more what people expect. There was a related problem where the user was confused about trailing slashes (RT complains but debconf should have complained instead).
