When interacting with a layer/channel
widget in a plug-in GUI, a temporary
procedure is spawned. Script-fu plug-ins
run a check for translation whenever a new
procedure is run, but there's none available
for "temp-procedure-number-?" which is
spawned by the layer/channel pop-up.
This causes a crash because
script_fu_script_get_i18n () assumes the
script object it receives is always valid.
This patch adds a g_return_if_fail () call
to script_fu_script_get_i18n () to prevent
future crashes, and makes sure the script
object is not NULL after
script_fu_find_script () is called in
script_fu_get_i18n_for_proc () to prevent
the initial call for temporary procedures.
