Hide or disable the volumes in GtkFileChooser

[Florian Hühn <florian huehn web de>]

Hi,

i have several entries of user mountable devices (e.g. network shares) in my fstab.
All these volumes blow up the left side of the file chooser so i have to scroll down everytime i want to access a bookmark.

Is there any way to prevent the volumes from showing up?
I thought this should be possible with a .gtkrc-2.0 file but i didn't find any hint how to achieve this.

Thanks for you help
FH

PS: Due to limited resources i didn't install the gnome control center, so i'll have to manually edit the config files.
