Xglamo loops and hangs (and crashed before)

Hi,
using Om 2008.8 with zecke-dev and -testing updates Xglamo seems to be unstable:
during lunch when closing an pygtk application (battery.py) X11 got stuck.
now with usb/ssh I see the following:
Xglamo sucks cpu time and doesn't accept new xclients, they just hang.
this is the tail of "ps uaxOT" output:

12:13 is about the time when it hung.
I just tried xdpyinfo before to check x client connects -- it hangs too.
pid 7711 (xset) read "xset s activate" some time before.
this is the Xglamo image:

known problem ?
which other data can I provide (I'll keep that Xglamo running for now) ?
checking ps output I also noticed that X11 got restarted (aka crashed) tonight,
because at 06:40 I still was asleep, so Xglamo crashed/exited at the idle phone
which just run "battery.py" using ppygtk. -- again from "ps uaxOT" :
