Hi,
I've just had my first segfault with ion :-(
This happens (it's reproducible) when I execute this script:
function to_layer2(cwin)
local region = nil
for _,r in cwin:screen_of():llist(2) do
if (r:name() == "WScratchpad") then
r:attach(cwin)
r:l2_show()
end
end
-- cwin:screen_of():lnth(2,0):attach(cwin)
end
(The script is most probably buggy itself, but shouldn't cause ion to
segfault)
