           Summary: Sparkle causing crashes upon testing for new version
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh PowerPC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: bmturner at optonline.net


ON several occasions Testing nightly builds Webkit will crash, typically once a day, with the crashing thread involving Sparkle. I have submitted reports at crash time for this problem. I also tried to disable this checking in 'org.webkit.nightly.WebKit.plist' by disabling SUEnableAutomaticChecks, which tonight didn't stop a crash. I have included this file from just  after the crash:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

I don't know is there is some incompatibility on my system that effects Sparkle, but this problem has happened over several nightly builds with similar crash reports.
