[PD] pd extended randomly crashes when I save

[Matteo Sisti Sette]

Hi,

Often when I hit ctrl+s to save a patch, my Pd extended crashes; it 
closes itself without any message at all.

Is there some place I can look at to find some log file or something 
that I can post, in order to provide further information?

It's Pd version 0.42.5-extended-20100601 for Ubuntu

By the way it crashes BEFORE it saves, so it's extremely critical

thanks
m.
