logjam is broken in rawhide because of the libsoup upgrade. Here are some
patches, which compile but are otherwise untested. (I don't have a LiveJournal
account to test it against.)
Alternatively, you might want to wait for bug 430756 (compat-libsoup).
I haven't filed this upstream because upstream seems to have abandoned it (and
because it's untested...)

patch for logjam to use libsoup 2.4
Seems to work great, thanks! Applied in rawhide.
