Sylpheed crashes with some actions

[RealVegOs]

I use version 3.8.0beta1 (Build 1187). I have configured many scripts in the Settings / Actions menu. When a > is involved to paste text into the composing window, e.g. cat path/to/text/file > Sylpheed crashes completely ( with all windows closing). I do not use this feature that much any more, but I think this is an old bug, present in former versions too. Could you please have a look at this?
