The "other" open/save file dialog has timeouts or causes QGIS to stop responding completely

Quantum GIS uses two open/save file dialogs: the normal Windows one and some custom one.

This custom one has major problems whenever I go to a directory that has shortcuts that are unresolvable. E.g., I have a shortcut to a folder on another computer. If this computer is off, or if I am on a different network, one of two things happen:

1. This file dialog takes forever and a half (approximately) before it shows the files in the directory. Eventually, it shows the contents of the current directory.
2. This dialog never, ever shows the contents of the current directory. I can cancel out of the dialog, but QGIS stops responding entirely. I found no way to get QGIS to respond again.

Can this "other" file dialog be discarded? Is there any reason why the standard Windows dialog is inadequate?

Here's an example where it happens: I do File > Save Image As. That custom, not-the-Windows-standard save file dialog comes up. It starts out on my desktop. It shows nothing in the desktop even though there are several directories and many files. However, the dialog is otherwise responsive.

I type out.png into the File name field, select png format from the Files of type dropdown, then hit Save. From then on, QGIS is unresponsive, and the out.png file is never written out.

QGIS never becomes responsive again. I must end its process manually.

OK, I can confirm that removing all shortcuts from the desktop fixed the problem. I don't understand why this other file dialog has to "exercise" the shortcuts. And I also question whether there's any value in this other dialog. What's wrong with the default Windows dialog?

Did this eliminate the nonstandard dialog from all places? I just noticed that SPIT still uses it in 1.7.3 when hitting the Add button.

No only "whereever possible", ie. not where customized dialogs were used - like where the user can specify file encoding or can "Cancel all".
