- try to ensure you have the debugging symbols for about all the libs
involved, run gdb --args elisa, type "run", wait for it to segfault,
type "thread apply all backtrace" and send us the output (on the mailing
list or in a bug report).
I don't have all the debugging symbols, but I can already send you this:

0x03ef2b23 in gst_element_register () from /usr/lib/libgstreamer-0.10.so.0
Aha! Looking at the stuff below, this happens in the main thread, and is
called by some python code. But gst.element_register() is broken in old
versions of gst-python. The only such register we still do is in
elisa-plugins/elisa/plugins/gstreamer/changestride.py (line 125), and it
is not needed since we don't use that element from the registry, but we
instantiate it directly (and we don't use it on linux anyway). So my
advice is: comment out the call to gst.element_register() and that
segfault should disappear. I'm about to do that in trunk.
Perfect. It does no longer segfault now, but we get to another batch of
problems ;-)
Some are related to plugins that have missin dependencies (which I am
aware of). I don't think these are fatal, but I cannot find how to disable
those plugins from the elisa configuration.
The generated config-file gives no clues what form the list should be in.
I tried this, but it fails:
disabled_plugins = [ 'ipod' ]
It would be useful if the generated config file would have a comment or
two ;-)
Now I end up with the following output. The screen is black after it
has shown the splash-screen. The splash-screen is flickering on my
i915-based laptop (I just realized this is because of compiz, no worries)
The screen stays black when this is on the terminal output:

From this output, it is hard to see which traceback is the fatal one. It
obviously is not the gpod/flickr stuff. But might it still be dbus
or avahi related ? Are these mandatory afterall ?
According to the README dbus was optional (and that was my main motivation
to try and get elisa working). If we could patch elisa to work with an
older dbus, would those patches be accepted ?
Would it be worthwhile to add the patch to "support" incompatible
python-dbus versions in one form or another ?
I have no idea how hard this would be, nor if someone has the time to do
it, but patches doing this would most certainly be considered.
In the thread from last night I added a small patch to do this. I attached
it to this mail. This simply disabled dbus support (much as would happen
when no dbus python module was found on the system).
Thanks again,
