You shouldn't need those. GNet does that automatically for you (as the stack 
trace shows as well). I don't have an explanation for your problem though I'm 
afraid - hfetch works fine here. Which GLib-2.x version and Gnet-version are 
you using?

If you want to retrieve stuff using http, you might want to check out the 
brand-new GConnHttp module, which you can find in gnet cvs (just copy 
conn-http.[ch] into your code and adjust the includes). GConnHttp works 
asynchroneously, so you don't even need threads to achieve that.
