Please describe the problem:
I have different news servers configured in Pan, one of them is GMane. When clicking o a group only present in GMane, Pan correctly downloads the headers, but the task is not removed from the queue when another server than GMane is not reachable. In a wireshark dump, I see that Pan continues to contact the unreachable news server every five seconds. While Pan is doing this, no new headers appear in the group, until I delete the task.

[problem also discussed in pan-users mailing list, subject Pan 0.120 only queuuing tasks"]

Steps to reproduce:
1. Configure two servers in Pan, for example news.gmane.org and an IP address on which no NTTP server is listening
2. Get new headers in a group from GMane, by clicking on the group in the group list


Actual results:
The status bar says: "Tasks 1/1", and headers are downloaded from GMane. The status bar changes to "Tasks 0/1". No new headers appear in the group. The task remains stuck in the queue. Wireshark shows that Pan tries to connect every five seconds to the server on which the NNTP port is closed.

Expected results:
Pan should immediately show new headers from the group, and the task should not remain in the queue. Pan could show a warning in the status bar that server XXXX did not respond.

Does this happen every time?
Yes
