Hi Jim,

I'm doubting this problem is rooted in the gnome-pilot code.  Try
googling for "closedir+0x28 double free", or even just "closedir+0x28".

Here's one posting that might give the flavour:
http://lists.digium.com/pipermail/asterisk-users/2007-February/179580.html

It might be worth trying to rebuild the gnome-pilot package on your
system, in case there has been some binary incompatibility introduced in
a system library (though I don't see anything obvious in your list of
updated packages).

I'd suggest you open a bug on bugzilla.gnome.org to track this, rather
than posting to this list.  Post a reference to the bug ticket here, so
people can follow the discussion if they want.

Other things to try, to generate more info: install the gnome-pilot-dbg
package to get a backtrace with symbols, and start gpilotd within
'valgrind'.  This will generate quite a bit of output but might catch
something significant.  You could attach the output to a bug report.

Regards,

Matt
