I'm running with python 2.4.3, dbus-1.0.1, and dbus-python-0.71 from the Gentoo repositories.  When I try to use introspection on the example-service.py (modified to use the SystemBus, but vanilla other than that), the python instance running the server crashes with a segmentation fault.  The code that triggers this is: >>> import dbus >>> bus=dbus.SystemBus() >>> obj=bus.get_object('org.designfu.SampleService', '/SomeObject') >>> obj.Introspect() The backtrace for the crashed python server is: (gdb) bt #0  0xb7ceda93 in strlen () from /lib/libc.so.6 #1  0xb7e32365 in PyString_FromString () from /usr/lib/libpython2.4.so.1.0 #2  0xb7b90b3e in ?? ()    from /usr/lib/python2.4/site-packages/dbus/dbus_bindings.so #3  0x00000000 in ?? () I'll be digging into this for a bit, but just in case, is Introspection on python-based dbus servers known to fail?  For comparison, the following python code: >>> import dbus >>> bus=dbus.SystemBus() >>> dbus_object = bus.get_object('org.freedesktop.DBus', '/org/freedesktop/DBus') >>> dbus_object.Introspect() gives me a nice XML listing of methods exported by the central DBus object (which I assume is written in C).  Any assistance would be much appreciated.
