Opening my gmail causes safari to crash, no crash report given?

Question

Hi. I have windows 7 x64 professional and safari 5.0.5 (7533.21.1). Everytime I try to login to my gmail email address, safari crashes and no crash report is given. I have tried loading it in different x32 and x64 bit modes, as administrator, and in compatibility mode. I've tried updating and since you cannot revert to previous version, I'm out of options. I tried re-installing and upadting all of my plugins also.
Please fix this asap.

Answer 1

many thanks.

If we take the problem report at face value, we're having trouble with an Apple Application Support program file. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try another uninstall/reinstall, this time taking out both Safari and Apple Application Support. We'll take some additional explicit precautions along the way. Best to print out a copy of these instructions because at one stage of proceedings you won't be able to use a web browser.
Preliminaries
Download and save a fresh copy of the SafariSetup.exe installer file to your hard drive. (Don't run the install on line, and don't start the uninstall just yet.)
http://www.apple.com/safari/download/
Quit any recent version of iTunes for Windows, QuickTime for Windows and/or the MobileMe Control Panel for Windows if you have them installed and open. (They all use Apple Application Support, and may interfere with the AAS uninstall if they are open.)
Uninstall Phase
Head into your "Uninstall a program" control panel. Uninstall Safari. Uninstall Apple Application Support.
(From this point onwards, recent versions of QuickTime, iTunes and the MobileMe Control panel will not launch, until we get AAS reinstalled by reinstalling Safari.)
Next we'll remove any left-over program files and folders.
In "Computer" open "Local Disk C:" (or whichever drive you have your program files installed on).
Open the "Program Files (x86)" folder.
Right-click on the "Safari" folder (if it still exists) and select "Delete".
Staying in the "Program Files (x86)" folder, open the "Common Files" folder.
Open the "Apple" folder.
Right-click on the "Apple Application Support" folder (if it still exists) and select "Delete".
Empty your Recycle Bin.
Reinstall Phase
Restart the PC. After the PC restarts do not open any applications. Disconnect from your network and/or the internet. Now switch off all your security software (firewall, antivirus, antispyware).
Now start the reinstall by doubleclicking the SafariSetup.exe file you downloaded earlier. (This should also reinstall Apple Application Support.)
Reenable all security software prior to reconnecting to your network and/or the internet.
Did the reinstall seem to go through properly? If so, try heading back to gmail. Do you still get the crash there?
