Public bug reported:

Today I tried to sync my iPod Touch using gtkpod, and discovered that
the program segfaults when the device is plugged in -- whether I start
gtkpod while it is plugged in or start it first and plug the device in
afterwards.

Here's the relevant output from valgrind:

==6295== Process terminating with default action of signal 11 (SIGSEGV)

This looks very much like this bug, which was recently fixed upstream:

http://sourceforge.net/p/gtkpod/bugs/323/

Could we get an updated package which incorporates this patch?

The bug seems to be related to parsing play counts written by iTunes on
the device.  I have verified that the workaround described here
(deleting the XML file with play counts from the mounted iPod Touch)
fixes the problem:
