Safari crashed and won't open due to "Safari Shared" plug-in failure

hello everyone,

my safari browser crashed rashes last week and won't reopen. I says it is due to the failure of the "SafariShared" plugin. I tried to open with different user, but still wouldn't open - although it was due to a different plug-in. any advise? I appreciate it.

And after spending the time to email myself the error report, opening it on my iPad, pasting it here, apparently it contains invalid characters and can't be posted. :-/ not sure how else to post it.
