Hi Jason, sorry to bother you again. But today on my laptop I faced a
similar problem. The software versions are the same as on my desktop
(kaa-base/kaa-metadata trunk, GTK+-2.22.1, PyGTK-2.17.0).

When running this test app (
http://www.vicarious.com.ar/~godlike/algo.tar.bz2) and trying to close it
from the WM, it freezes. Last strace lines show this:
http://paste.pocoo.org/show/326877/

The "Killed by SIGKILL" line corresponds to KWin killing the window since
it's not responding. This also happens on the main app I was developing. I
do not see this behaviour if I start and end the main loop from inside GTK+,
only if I do so from within Kaa.

Do you have any ideas as to what is causing this? I'm quite puzzled, since
versions are the same as on my desktop.

Thanks
Juan Manuel
