The FTBFS bugreport against your package might be wrong, there has been
a problem in curl, at least since 7.18.2-3 that was finally fixed in
7.18.2-5. Please try to build your package with the latest curl packages
and seee if the breakage indeed is related to that curl bug or if the
FTBFS against your package is justified.
