transient windows are being weird?

Hello, i just installed a newer version of the ion window manager  
(20070203), but
every time a window that's a subwindow for some application comes up  
(those are
called transient windows right?) nothing happens, however when i try  
to close that
window, it turns into a black thing and ion hangs and i have to restart X.

I am not sure what is causing this problem but i can "solve" it by  
just making a
lot of winprops which set float=true for said windows.  However it is  
quite abit
of work to set all those kludges and not all programs give an explicit  
instance-name
for all dialogs, so i am kinda stumped :(

If anyone knows of this problem or knows how to fix it or knows how to  
debug it
i'd like to hear it!

ps. i made ion dump core after it hang by doing sleep 10 && kill -12  
"ion3" and
then making it hang, i have the core laying around somewhere but i'm not
sure how to get more info out of it then this:

It seems like ion gets stuck somewhere after trying to print "object destroyed
while actions pending" (something like that) because i am not seeing  
those messages
anymore (ion used to give me those quite a bit when i used 20061223)  
and that is
kind of what is happening.  But i am not sure why or how to get more  
info from gdb :S
please help! :)

ps2. I'm not sure if it's an ion, because i also installed a newer version of
freebsd (6.2), but other window managers seem to have no problems?

ps3. Is there a way to see if one window is a child window of another
window without using winprops?
