            Bug ID: 143245
           Summary: Crash when WebCore::SQLiteFileSystem::openDatabase is
                    called from multiple threads
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at igalia.com

With WebKitGTK+ 2.8.0, the UI process likes to crash when multiple threads call WebCore::SQLiteFileSystem::openDatabase at the same time.  I never understood sqlite3 thread safety but a reasonable guess is that we're doing it wrong.
