Thanks to reefyrob for discovering this crash.

On puzzle 1022, checking "Show" for the disulfide filter crashes the client on Windows. This happens on the initial pose and seems to affect all poses, regardless of whether a disulfide bond exists.

(Due to some debugging confusion, a 1022 solution was shared with scientists with the suggestion that this was an example of the "angle range error" issue described in http://fold.it/portal/node/1998668. This is not correct. Solutions for puzzle 1022 have hit the angle range error issue, but not reproducibly.)

With the disulfide checkbox issue, after the crash, debug.txt contains lines like:

"current_tool" : "Selection Interface"
"file" : "core/conformation/Conformation.hh:306"
"message" : "seqpos <= size()"

while log.txt ends with
