I saw a similar problem with the last couple of
glibc 2.3.1 packages on debian ppc sid. If I visited
http://news.bbc.co.uk which has a java news ticker
mozilla would crash on the next hyperlink I tried
to visit (or if I clicked on one of the links shown
in the news ticker). I found that making my own
glibc 2.3.2 packages (which include the 2.3.1-14
necessary 2.3.1-14 patches) has eliminated these
crashes and jdk 1.3.1 is rock stable again.
