            Bug ID: 144953
           Summary: WebKitNetworkProcess segfault when using tmpfs
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs

tmpfs doesn't support user_xattr on Linux. Therefore, if an user have its ~/.cache/epiphany on tmpfs, setting xattr::birthtime fails. When WebKit tries to read the value back in Source/WebKit2/NetworkProcess/cache/NetworkCacheFileSystemPosix.h, it will pass a null pointer to g_ascii_strtoull. This can cause segfault in WebKitNetworkProcess.
