            Bug ID: 232435
           Summary: [WPE][Qt] String memory leak in WPEQtView.cpp
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit API
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: aperez at igalia.com

In WPEQtView.cpp currently there is something like this, around line 435:

    variant.setValue(QString(g_strdup(strValue.get())));

Note that the pointer returned by g_strdup() is not freed, and the QString
constructor makes a copy of the string. Not only this makes one uneeded copy,
but also the one done by g_strdup() gets leaked.
