Please describe the problem:
After an indeterminable period of time after being launched, Evolution will no longer communicate with the Internet. Internet connection is fine, all other applications can access it without any problems, but Evolution will hang trying to load images or upload/download new messages. This behavior appears most likely to happen after importing messages, after creating new message-filtering rules, or simply after being left open for a few hours. The only remedy is to shut down and restart Evolution.

It is important to note that Evolution itself does NOT appear to be hung at any time. It just simply acts like it cannot find an internet connection and waits indefinitely for one to appear. Evolution does respond appropriately to user cancellation of image downloading or connection attempts to POP3 servers.

Steps to reproduce:
1. Import message folders; or
2. Create new message filter rules; or
3. Leave Evolution running for a few hours; or
4. Launch Evolution, have preview pane open, click on message with embedded images, then click on a different message before images in first message have finished loading.


Actual results:
Evolution loses network connectivity. All other applications can access network resources and Internet normally except Evolution. Image loading and attempts to connect to POP3 servers will hang, requiring manual cancellation.

Expected results:
I expect Evolution to download images and connect to POP3 servers whenever an Internet connection is present.

Does this happen every time?
#1 happens usually; #2 and #3 happen unpredictably; #4 happens always.
