Hi,
I'm attempting to use maemo-launcher on some generic ARM embedded
hardware which doesn't run the full Maemo library stack, and I've run
into a couple of problems.
First, there's the bug about gdk_display_close() which is mentioned in
the README file, which results in the daemon process crashing as it
tries to run the Gtk booster. The underlying GDK bug is fixed in
upstream Gtk+ >= 2.10.
There's also something strange happening to the forked child
processes. The symptom when one executes the 'gtk-demo' program
(relinked to export its 'main' symbol):

--->8---
This same trouble doesn't appear when I use the summoner [nor when I
run the daemon without the Gtk Booster], so I'm reasonably sure that
the trouble is related to the Gtk booster.
The relevant libraries in my build here are stock Glib 2.12.0, Gtk+
2.10.6, and Pango 1.14.5. Are there any particular patches applied to
Maemo's build of Pango, which are known to be required by the
maemo-launcher? Alternately, it looks like the trouble reported by the
various Pango functions above could be caused by an invalid
GtkSettings object. Perhaps there's some other relevant bit in the
Maemo fork of Gtk+ which I should be including?
Thanks,
Matt
