User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.6) Gecko/20050323 Firefox/1.0.2 Fedora/1.0.2-1.3.1

Description of problem:
Using the i386 rpm of firefox on my x86_64 box, I get a popup error window when I type CTRL-O or perform any other action that invokes the Gnome file browser, such as browsing files for upload. It contains the text

Could not retrieve information about file:///<whatever>: error accessing 'file:///<whatever>': Invalid URI.

The x86_64 build does not have this problem. Also if I enter file:///<whatever> in the url bar at the top however, it works fine as well. 

I suspect a missing i386 version of a library which the dependency checking in rpm is missing as I have the x86_64 version.  

Version-Release number of selected component (if applicable):
firefox-1.0.2-1.3.1

How reproducible:
Always

Steps to Reproduce:
1. Open 32bit version of firefox
2. Press CTRL-O
3.
  

Actual Results:  See error popup

Expected Results:  See Gnome file browser popup. If click through the error, the file dialog does appear but the error popup appears again if you click on anything in the left hand pane.

Additional info:

The problem arises even with no extensions or plugins loaded and with a new profile.
