Point taken :-)
Now i am testing for NULL but i still get the same problem. However,
i do not think this is the probelm because if i step thru the
program with ddd, just before it segfaults at the line 

mePtr[i].appname = strdup(uri);

If i hover the mouse over the previous line:

uri = xmlGetProp(cur, "name");

It shows me that the value of uri is "Netscape Navigator"

Also, if this was the case (and i wish it was cos then i could fix
it :) then that would apply to the directory where the code works in
as well as any other directory.??

thanks for pointing out testing for NULL though.
