If this isn't immediately reproducible in an unconfigured copy of sylpheed
(I haven't tried yet, I don't use it myself), then we'll need more
information than this to be able to diagnose what's happening. Please
quote the whole backtrace, preferably after installing debugging
symbols for pango, sylpheed and any other libraries that show up in the
backtrace.

My understanding had been that the preferred representation for that is to
reassign the bug to *both* packages ("reassign -1 libpango-1.0-0,sylpheed",
"found -1 pango1.0/x.y.z", "found -1 sylpheed/u.v.w"), which avoids having
to either duplicate relevant information between the two bugs, or have
the information only show up in one of the two places.
