When I try to save a file in Firefox, a dialog comes up. There is an option to "Browse for other folders." Clicking on this drops down a browsing area. It flashes to a normal size but shrinks immediately to showing about two files/folders in the selected directory. Hiding and expanding will cause the dropdown to open at the correct size. Sometimes it does this on the first retry, sometimes it takes multiple attempts.
This happens with any dialog of that sort.
Also happens in Thunderbird.
Also happens in OpenOffice.org.
Also happens in Gedit.
Kind of related, when the dialog comes up now, the home folder and desktop shortcuts on the left have no text or icon and are about 1/4 size. Moving folders fixes it.
I was able to reproduce this on Ubuntu Edgy.
Reproduction steps:
1. Start Applications > Accessories > Text Editor
2. Go to File > Save As...
3. Click on "Browse other folders"
Expected result:
The window grows to show a list of files and directories.
Actual result:
The window grows, and then shrinks to its minimal size.
Toggling "Browse other folders" a few more times makes it behave as expected. Closing and re-opening the dialog box does not reproduce the bug. You have to quit and restart the application to trigger it again.
