I've seen this happen in 0.23-fixes when the MythXML/http server is
"overstressed"--i.e. I can cause it on demand by deleting all the PNG
thumbnails from my backend servers and then going to the MythWeb
Recorded Programs page (and it will fail after some huge number of
previews are generated). Unfortunately, I haven't looked into tracking
it down since I've been busy with other stuff and (at least on my
system) it's easy enough to avoid triggering it by not doing that.
