Hmm, is your epg-debug output as innocent as the one that the original
reporter provided?

Currently, I suspect that the code in the following clause might be
skipped:

(unless epg-process-filter-running ...)

Can you insert debug-prints in epg-wait-for-completion?  It would be
something like:

(message "epg-process-filter-running: %S" epg-process-filter-running)
