Comment 1 Jeremy Katz 2007-06-11 15:14:22 EDT

This is almost certainly not a python bug and instead a bug in one of the
bindings used by luma.  Python2.5 changes things so that you must consistently
use either PyObject or PyMem allocation rather than mixing and matching between
the two.  

Would need a backtrace with -debuginfos installed to get a better idea of which
is the causer.  Or a good way to set up luma to use it.

Backtrace of the python issue

Comment 3 Jeremy Katz 2007-06-11 15:42:15 EDT

Okay, that's coming from PyQT (or what's generated by sip)

Comment 4 Jochen Schmitt 2007-06-12 11:58:35 EDT

I have found out, that the issue was raise by python-ldap. After a update to
python-ldap-2.3 the issue doesn't occure anymore.
