[R] htmlParse hangs or crashes

Dear colleagues,
each time I use htmlParse, R crashes or hangs.  The url I'd like to parse is included below as is the results of a series of basic commands that describe what I'm experiencing.  The results of sessionInfo() are attached at the bottom of the message.
The thing is, htmlTreeParse appears to work just fine, although it doesn't appear to contain the information I need (the URLs of the articles linked to on this search page).  Regardless, I'd still like to understand why htmlParse doesn't work.
Thank you for any insight.
Simon Kiss
