           Summary: [GTK] KURL::fileSystemPath() doesn't work if uri
                    contains #
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC

The problem is that  KURL::fileSystemPath() uses g_filename_from_uri() to convert the uri to a local path. g_filename_from_uri() doesn't allow uris containing #, returning NULL in that case with a G_CONVERT_ERROR_BAD_URI error. 

In WebKit2, when html has been loaded from a string with loadHTML(), all relative paths must be relative to the baseURL passed to loadHTML(). To check whether a relative path is in the same directory than the baseURL, both are converted to local path. If the relative path contains a # KURL::fileSystemPath() returns an empty String and the condition is always false, making the web process to terminate. 

The solution is using GFile instead of g_filename_from_uri(), since GFile removes the anchor from the uri when converting the uri to a local path.
