Hi folks,
 I've been having trouble with the Firefox driver on OS X:  My tests   
 run just fine against Firefox 2, but hang when running against Firefox   
 3.  I've played around a bit in the debugger, and it looks like the   
 call to clean the Firefox profile never returns.
 
I've tried opening up the terminal, setting the appropriate   
 environment vars, and running the same command that webdriver does:
 
dbriones@neo:~>export XRE_PROFILE_PATH=/tmp/webdriver4439profile
 dbriones@neo:~>export MOZ_NO_REMOTE=1
 dbriones@neo:~>/Applications/Firefox\ 3.app/Contents/MacOS/firefox-bin   
 --verbose -silent
 dbriones@neo:~>2009-03-03 09:28:40.695 firefox-bin[1837:10b] ***   
 _NSAutoreleaseNoPool(): Object 0x1a17900 of class NSCFString   
 autoreleased with no pool in place - just leaking

...followed by several screens full of messages similar to the last   
 one; the object IDs and types vary.
 
Interestingly, I only get this result when I pause the test at a   
 breakpoint right before it would execute the command and then attempt   
 to run the command manually.  If I then kill the manually launched   
 instance of FF and the test itself, then attempt to relaunch FF in the   
 same way, FF runs without complaint.
 
Is anyone else seeing this?  I took a look at the automated build for   
 Firefox on OSX; the build seems broken, but I can't figure out how to   
 see what caused the breakage:
 
http://xserve.openqa.org:8080/job/webdriver-firefox-os-x/
 
By the way, I'm running against jars built from rev. 851 of trunk.
 
Thanks,
