For some unknown reason, the plugin detect NETWORK_UP only without
NETWORK_DOWN, with "networks" being NULL, causing the segfault. Should
protect this by checking the value of networks before calling
g_hash_table_foreach.

Title:
  xchat-gnome crashed with SIGSEGV in g_hash_table_foreach()

Status in “xchat-gnome” package in Ubuntu:
  New

Bug description:
  I'm using the latest Oneiric (upgraded daily from beta1). Xchat-gnome
  crashed when I disconnect and reconnect to a WIFI AP (to refresh my IP
  address). Not sure if this would trigger the crash always. File a bug
  first and would try the same operation later to confirm.
