Please describe the problem:
After having Epiphany open for a few days, it will eventually stop loading web pages. Any attempt to load a web page results in the browser just reporting "Loading..." indefinitely. It doesn't matter if it's refreshing a current page, clicking on a link to navigate to a new page, or typing a URL into the location bar.

After it gets into this state, no new pages can be loaded. If I close down all epiphany windows and reopen epiphany using the Ubuntu applications menu, the new window that comes up still has this problem. It's only after I do a "killall epiphany-browser" and a restart that I am able to load web pages again.

While in this state, an strace of the epiphany-browser process shows the following loop:

poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=11, events=POLLIN|POLLPRI}, {fd=12, events=POLLIN|POLLPRI}, {fd=13, events=POLLIN|POLLPRI}, {fd=16, events=POLLIN}, {fd=10, events=POLLIN|POLLPRI}, {fd=42, events=POLLIN}, {fd=20, events=POLLIN}, {fd=21, events=POLLIN}, {fd=22, events=POLLIN}, {fd=14, events=POLLIN}, {fd=34, events=POLLIN}], 14, 9) = 0

gettimeofday({1220380766, 35031}, NULL) = 0
read(34, 0x8b5b14c, 4096) = -1 EAGAIN (Resource temporarily unavailable)

System details: Ubuntu Hardy 8.04.1, epiphany-browser 2.22.2-0ubuntu0.8.04.5.

Steps to reproduce:
1. Run epiphany for several days
2. Click on a link, or type a URL into the location bar
3. Notice that it never starts loading the page and just says "loading..." indefinitely


Actual results:
The pages never start loading.  When this condition occurs, it happens for every tab in every open instance of Epiphany.

Expected results:
The browser should continue to function as normal.

Does this happen every time?
I can't reproduce it except by keeping a copy of Epiphany open for many days at a time.
