Bug 154073

Description of problem:

I regularly have gpilotd crashes when synchronizing via USB to a Palm Tungsten
E, particularly the second time I sync since booting the computer.  These
crashes happen during the sync of calendar.  They are particularly annoying as
the palm locks for a while and it or gnome-pilot thinks that is has synched
completely, so next time I go to sync it will not pass the information from the
last crash.

Crashes appear to be associated with the famous timeouts.

usb 1-3.4: gpilotd timed out on ep0in
usb 1-3.4: gpilotd timed out on ep0in

Version-Release number of selected component (if applicable):

gnome-pilot-2.0.12-4
gnome-pilot-debuginfo-2.0.12-4
kernel-2.6.10-1.770_FC3

How reproducible:

often

Steps to Reproduce:
1. Not easy to say.  Usually happens the second time I synchronize, possibly
because the timeouts have already occurred.
2.
3.
  
Actual results:

crashes and messes up future sync's

Expected results:

sync

Output of gdb backtrace is below.
