I have this crash with Hardy Beta. To find out what happens I recompiled
the program. Here is the backtrace:
Program received signal SIGSEGV, Segmentation fault.

Looking at xfae_item_new() in xfae-model.c, item is only allocated if
"Type" is "Application", but at the end of the function passed to
xfae_item_free(), where it is dereferenced, also if it is NULL. To
reproduce the bug, you only need a desktop entry with a "Type" which is
not "Application", e.g. adept_notifier_auto.desktop:
grep -n "Type=Service" /etc/xdg/autostart/*
/etc/xdg/autostart/adept_notifier_auto.desktop:21:Type=Service
Here's a little patch to fix the bug:
