Problem when debugging Mozilla 1.7.5 in Suse 9.2

Hi everyone,

I'm trying to debug Mozilla but I got some problem...
After `prun' gdb command Mozilla is lauched and gdb freezes without
show any prompt.

As we can see bellow, gdb is loading `/lib/tls/libthread_db.so.1' instead
of `/lib/libpthread.so.0', however I don't know whether it is a problem...

---- END OUTPUT ----

It is the `prun' gdb function:
# run when using the auto-solib-add trick
def prun
         tbreak main
         run
         set auto-solib-add 0
         cont
end


Does anyone knows what is going on? How can I fix it?

Thanks an advance.
