[Sage] Sage feed checking just dies/stalls randomly on same link

[Stefan]

Hi: I have been having this problem with Sage for months now.

Occasionally, when traspsing thru my RSS feeds, the check will just stall. 
I figure its a dead bookmark, so I move it out of the way, and then it 
will stall on a completely different feed/link.  I move *that* one out of 
the way (or just delete it) and it will stall again, in another totally 
random place.  Its as if my bookmarks file is corrupted or something.

This will go on for days or weeks,  or until I delete so much of my 
bookmarks, it will start working to the bottom again.

The only way to get it to restart the checking is to close the Sage pane 
and re-open, have it check feeds, and it just stalls again on the same 
link.

Any suggestions?? Any logging I can look at?? This is driving me insane... 
I have come to live+die on Sage, and these outages are painful. :(

Im running FF 1.505 and the latest Sage version.

Thanks,

Stefan in Boston
