Is the bug in my descriptor or the parser?
In testing it took a little bit of finagling to get chutney to accept a non-Tor "platform" item in the descriptor. Turned out adding a "proto" line as well is enough. But it did occur to me that other code may assume the "platform" line takes a certain form.
I can easily change the descriptor if necessary? I've included it below for reference:

So it's already finding bugs in other implementations?
That's pretty awesome! ;-)

Looks like this issue is caused by a server descriptor produced by an alternate Tor implementation that identifies itself as `"platform Pearl 0fd5756 on Linux"`. And that implementation uses a different order of elements in its descriptor.
