With Qt 4.8.1 I do get "timeouts" as well: when requesting the "Open 
file" or "Save as" dialog the application GUI freezes for a couple of 
seconds (about 10 seconds), but nothing happens thereafter: no file 
dialog appears (the application continues to respond to mouse and 
keyboard events however).

However this ONLY seems to happen if the application is SANDBOXED!

When I run the application from within Qt Creator (non sandboxed) Open 
and Save dialogs show just fine (for Open I use exactly the method as 
mentioned above).

In earlier releases (Qt 4.8.0, Qt 4.7.x for sure) Qt even crashed, see

   https://bugreports.qt-project.org/browse/QTBUG-21609

Now I cannot remember whether my sandboxed application did work under 
Lion (with Qt 4.8.1) and whether this behaviour has now changed again 
(at least it doesn't crash anymore ;)), but according to above QTBUG the 
final solution will be in Qt 4.8.3 only anyway (it might also work in Qt 
4.8.2, but that one is not offered yet via QtSDK Updater...).
