Description

In some circumstances (or types of borken links), all attempts to use Constellation file dialogs, such as "File->Open" and "File->Save As..."

Mutliple references to the Netbeans issue can be found, such as:

We have identified that deleting broken links from the desktop, either from "C:\Users\\Desktop" or "C:\Users\Public\Desktop" has resolved the issue. NOTE: the particular type of broken links that triggers the issue is not currently understood and needs to be investigated as well.

This ticket is raised to see if we can:

identify the type of broken links that causes the issue to occur
write some code to test for this scenario and warn the user

Steps to Reproduce

Identify the types of broken links that trigger the issue
Open Constellation and create a new graph
Select File->Save As... and attempt to navigate through the file system.

Behaviour

Expected behaviour: No noticable slowdown

Actual behaviour: File dialogs can take 30 seconds or more to navigate

Reproduces how often: Dependant on type of broken links
