[   INFO] subscription: 0001: "epggrab" unsubscribing

Very very strange... I added more traces to epggrab (in latest), but could you also add this line:

diff --git a/src/subscriptions.c b/src/subscriptions.c
index 7bafb89..c4f72c3 100644
--- a/src/subscriptions.c
+++ b/src/subscriptions.c
@@ -530,6 +530,7 @@ subscription_unsubscribe(th_subscription_t *s)
              s->ths_title, channel_get_name(s->ths_channel));
   } else {
     snprintf(buf, sizeof(buf), "\"%s\" unsubscribing", s->ths_title);
+    if (!strcmp(s->ths_title, "epggrab")) abort();
   }

   if (s->ths_hostname) {

I would like to see, where it crashes (need to know the caller of the unsubscribe fcn)...

Just a note, the correct epggrab shutdown sequence should be like:

2014-11-21 11:19:45.000 [  DEBUG] epggrab: grab done for 235.10.10.16 in Tralala (timeout)

... not only one "unsubscribe" line...
