The file open dialog will cause applications to crash. I believe this is 100% reproducible.

1. Download and install LibreOffice 3 (3.5.7.2, Build 350m1).
2. Run LibreOffice (but FireFox is equally at risk).
3. Create a new document; write a few characters; save it.
4. Select File >> Open.
5. Leave the "Open" dialog open.
6. Browse to the $HOME directory.
the 
You should have a file dialog open at this point. Next:

1. Open a shell.
2. Change to your home directory.
3. Copy a rather large .zip file (1 GB) to your home directory (ensure the .zip file has only one file within it, and will extract directly into the home directory -- no subdirectories allowed).
4. Unzip the .zip file into the home directory.

Expected Results

The application (LibreOffice) remains open and the user can select a file in that directory.

Actual Results

Crash.
