[support] teaser trimming sometimes not working

[Cameron Gregg]

Hi All,

I've noticed sometimes that when the teaser gets created it doesn't 
apply the trimming length I have set (600 chars). It only happens 
sometimes, and I'm baffled to what is causing this. Is this a known 
problem? is there a fix?

drupal version. 4.6.5

you can see the effect I'm talking about here:
