[lxml-dev] [BUG] lxml-2* hangs on interpreter shutdown with gtk-mainloop

Hi,

I'm developing a PyGTK-application that uses lxml to validate plugin-XMLs.
After upgrading to lxml-2*, I noticed, that my application is not shut
down correctly (i.e. I close the application, but it still runs in the
background).

After evaluating a little bit, I got the test case attached. This case
hangs at the end: Example output:

necoro at Devoty ~ % ./test.py
lxml.etree:        (2, 0, 2, 0)
libxml used:       (2, 6, 31)
libxml compiled:   (2, 6, 31)
libxslt used:      (1, 1, 22)
libxslt compiled:  (1, 1, 22)
Destroy...
Destroyed
Now after the GTK-Main ... So the main has finished

Important notes:

- - it does not hang if I use etree.XML instead of etree.parse
- - it does not hang if gobject.threads_init() is not called
- - works with lxml-1.3.6

A quick glance with gdb:
(gdb) bt
#0  0xb7f97410 in __kernel_vsyscall ()
#1  0xb7e5248e in sem_wait () from /lib/libpthread.so.0
#2  0xb7f1ea38 in PyThread_acquire_lock () from /usr/lib/libpython2.5.so.1.0

(No further information as I don't have debug information in all my
libraries ;))

Would be great, if anyone has an idea or is able to fix it :)

Regards,
Necoro
