Thanks again for your suggestions. Passing endpoints= doesn't seem to do
anything.
	>>> import stem.descriptor.remote
	>>> BIFROEST = ("37.218.247.217", 80)
	>>> print list(stem.descriptor.remote.get_server_descriptors("C8CBDB2464FC9804A69531437BCF2BE31FDD2EE4", endpoints=(BIFROEST,)))
	[]
It also doesn't work when trying the fingerprint of another default
bridge, or of one I just got from bridge.torproject.org.
	>>> print list(stem.descriptor.remote.get_server_descriptors("A09D536DD1752D542E1FBB3C9CE4449D51298239", endpoints=(BIFROEST,)))
	[]
	>>> print list(stem.descriptor.remote.get_server_descriptors("924E408BAE68C6C47A06BCDF6A44A53930708092", endpoints=(BIFROEST,)))
	[]
I get the same output with and without the endpoints= argument, and
whether or not I provide the SHA-1 hash of the fingerprint.

Strangely, this call seems to just hang:
	>>> print list(stem.descriptor.remote.get_extrainfo_descriptors("499D92E08769BFC0B7941C74031335B9EC9E9BAE", endpoints=(BIFROEST,)))


I tried some other things in Stem but none of them worked.
