            Bug ID: 221377
           Summary: [WPE] fast/text/hyphenation-unknown-locale.html is
                    asserting in debug since added
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WPE WebKit
          Assignee: webkit-unassigned at lists.webkit.org

fast/text/hyphenation-unknown-locale.html

Crashes in Hyphenation.cpp lastHyphenLocation, ASSERT_NOT_REACHED. (trace below)

GTK enables usage of libhyphen, while WPE does not, falling back to this stub.

Should WPE expose an option to use libhyphen, like GTK?

Skipping in debug mode while this is sorted out.
