Description of problem:
I have set in the preferences of the ogo mailer to show 500 mails in a list. When I then enter a folder with a lot of mails, and leave it there, then after some reloads of the page the ogo instance dies with the following exception:

Application Server caught exception:

  class:   ObjcRuntimeException
  name:    ObjcRuntimeException
  reason:  Objective-C runtime error: Virtual memory exhausted

  info:
    

When I choose the next smaller value in the preferences, then it only takes some reloads longer to exhaust all memory, maybe a memory leak.

I took a look with top on the instance serving the webui I am using, and were clicking through about 200 mails in a folder with about 4000 mails, using the "next unread" button, added 10M of memory usage to the process. jumping between folders, especially with folders with lots of mails, raises the memory usage too.



Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.set the number of mails to show in a list to 500 in the ogo webmail preferences
2. open top and concentrate on the ogo instance that serves your webui
3. open a folder in the web mailer with a lot of mails, preferrably more than a thousand. 
4 wait and watch to the top output and see the memory usage growing

    

Additional info:

any idea on how to find out where the leaking happens?
