[news.eclipse.platform.swt] Help with no more handles error

[Andrea Desole <e_news@xxxxxxxxxxxxxxx>]

I'm trying to install the HTML Editor plugin, and I seem to have 
problems in making SWT work with Firefox.
So far I did the following:

export MOZILLA_FIVE_HOME=/usr/local/firefox/lib (Eclipse was complaining 
about the variable not being set)
added /usr/local/firefox to ld.so.conf, followed by ldconfig -v (to find 
libxpcom.so)

But I now have a problem I can't solve. I get the following stack trace:

the problem looks related to the way STW deals with Mozilla/Firefox, but 
I don't know exactly how. I have an old machine (Pentium 4 1.8 GHz), so 
everything must be 32 bits
Can anybody help me?
Thanks
