Yes, it's weird: a podcast in gpodder.net without url! search for Linux Outlaws, you'll only see the first 3 gpodder.net search page shows way more.

Traceback (similar with gtk3 branch...)

1485726984.299862 [gpodder.log] ERROR: Uncaught exception: Traceback (most recent call last):
  File "src/gpodder/gtkui/desktop/podcastdirectory.py", line 267, in update_ui

  File "src/gpodder/gtkui/desktop/podcastdirectory.py", line 58, in load
    entry.subscribers, cgi.escape(entry.url)), entry.title, entry.url))
  File "/usr/lib/python2.7/cgi.py", line 1043, in escape
    s = s.replace("&", "&") # Must be done first!
AttributeError: 'NoneType' object has no attribute 'replace'

The fix: don't show results that don't have entry.url.

We might want to do this server-side. Pinging @stefankoegl
