My laptop running Opensuse 13.1 x64 with the KDE desktop which is not always connected to a home network where a NAS device resides (connect via CIFS autofs).

When not connected to the NAS the KDE applications work as expected. But the GTK applications, namely Firefox and LibreOffice hang after clicking on "open file" while they search for the NAS which is not available from remote locations. The hang occurs when the dialog/window appears on screan to open/browse for a document/file to load.

How can I correct this issues with these GTK applications?
