Thanks for the feedback.
About the seg. fault, could you have a quick look with strace, to try to see where the crash occurs?

Very strange...
If you have some time, could your try to execute step by step the content of the main script (should be in /usr/lib/python2.5/site-package/papywizard/scripts/main.py)... Maybe the problem is when importing a module?
Thanks,

So the following segfaults:
Code:
import sys from PyQt4 import QtGui import hildon qtApp = QtGui.QApplication(sys.argv)

Great! Thanks!
Is this hildon module obsolete in maemo 5? In fact, I only use it to detect the plateform, in 2 modules:
and
Is there another way to detect the maemo plateform?

The other problem is I want to share the same code with maemo4 (N8x0)...

Otherwise I guess you could try importing PyQt4.Maemo5, and, if that fails, try importing hildon. That should cover both cases, providing you make sure that the Maemo5 .deb file includes the correct dependency to pull in the python2.5-qt4-maemo5 package.

Ok, but I still have the problem importing hildon before creating QApplication...
I have an idea; could you make the following test? In the config.py module, replace:
with
Does it work?

If you *really* need it only for identification purposes, the platform module might come handy:
EDIT: to avoid confusion - the second string in the tuple is a hostname. Ideally, we could use platform.dist() but sadly that one is not entirely accurate

Code:
>>> import platform
>>> print platform.uname()
('Linux', 'Nokia-N900', '2.6.28.10', '#1 PREEMPT Wed May 26 00:24:03 EEST 2010', 'armv7l', '')
...
>>> print platform.uname()
('Linux', 'Nokia-N810-23-14', '2.6.21-omap1', '#2 Tue Oct 14 11:25 EEST 2008', 'armv6l','')
