Pull request inbox sometimes not showing more than 10 results

Sometimes the Pull Request Inbox doesn't show more than 10 pull requests. No errors are shown in the logs. For me it is reproducible only once for each user, by the time the user logs in for the first time.

Using Firefox 32.0.3 in OSX
Steps to reproduce:

1. Created 1 branch from master (feature/1.0) and applied a change to it.
2. Created another 11 branches (feature/1 to feature/11) from master.
3. Created 11 pull requests, from feature1.0 to the other branches, adding another user as a reviewer.
4. Logout with the user who created the pull requests, and login with the reviewer.
5. Click in the Pull Request Inbox and check there are only 10 pull requests listed, despite the number in the icon shows there is 11:
   
   Notice it doesn't indicate in the bottom that there are No more pull requests.

After logging out and in again with the same user, the list is full:

With logs in debug mode, all the information I could see related to inbox is the following, but I'm not sure it is related to rendering the content in the Pull Request Inbox:

Also happens in Chrome - version 37.0.2062.124:

• I also tested logging with another user for the first time in Chrome, and the error is present there too, same way as in Firefox (it seems it doesn't load fully also, as the No more pull requests message is not there).
• After logging out and in again, the issue is gone.

The browser's console only mentions a deprecated method, but this is shown with or without the issue in place (both for Firefox and Chrome):

Workaround
If the issue persists even after logging out and in again, currently the only workaround is to look at the Pull Requests list directly into the repository:

1. Go to Repositories in the top bar > click in the repository name.
2. In the left panel click in Pull Requests.
3. Look at the tab Open for your opened Pull Requests.
