Hello Nagappan,

I'm doing fine, thanks. Still working on GUI automation.

I tried the GTK_MODULES trick you suggested, but to no avail. At first, there
are no errors, is just that the ldtp script freezes and there's nothing else to
do. However, if you wait long enough you get an 'Invalid response packet' error
(please have a look at ldtp.out).

As I said before the same set of subprocess.Popen invocations work correctly if
the calling script doesn't make use of GTK so there's an interaction problem there.

Please see the two files attached as an example:
- gedit.py: just opens gedit and closes it
- launcher.py: Launches gedit.py either from console or from gtk. For the gtk
version, please remember to use the '-g' option and to press the 'Launch LDTP'
button to call the gedit.py script.

As you will see when you call 'launcher.py' everything works correctly, but when
using 'launcher.py -g' it doesn't (ldtp.out). Please let me know if you have any
other advice.

Will try these today at work.

By the way, I'm using Ubuntu Karmic and LDTP 1.7.1.

At work, we are using LDTPv2 in Ubuntu 9.04 without any issues, can you please give a try with it ?

Thanks
Nagappan

Best regards,
