[Linux]Cannot view any news feeds after reading 3-4 feeds

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install snackr  (http://snackr.net/)
2. Read three feeds in quick succession (click -> wait for feed window to
show up -> click on next feed article)

RESULT:
After reading 3 or 4  feeds, new feed articles do not  show up in a pop up
window

Following callstacks are seen when the issue is reproduced:

Error: Error #3200: Cannot perform operation on closed window.

        at mx.effects::Tween$/timerHandler()
        at flash.utils::Timer/_timerDispatch()
        at flash.utils::Timer/tick()

So, what is happening here is that the application creates a window when
you click on a feed - however, it also nullifies the last window created
via your last click. Now the tween effect tries to show the closing
animation of the last window but throws an error when it finds that window
has already been set to NULL.

EXPECTED:
User should be able to read all feed articles

What is the expected output? What do you see instead?

What version of the product are you using? (Note: if you pulled the source
from SVN, enter a revision number here instead of a Snackr version number)

On what operating system?
Linux Ubuntu 9.10, FC12, OpenSuse11.2

What version of the AIR runtime do you have installed?
AIR2 Beta

Please provide any additional information below.
