+From http://bugreports.qt.nokia.com/browse/QTBUG-8365
+
+Starting a QtEmbedded-4.6.2 application linked against uClibc 0.9.30.1 results
+in an immediate segmentation fault.
+This is due to an incompatibility of the uClibc with the standard libc about
+the "realpath" function. The man of the function clearly specifies that
+"if resolved path (the second argument) is NULL, then realpath uses malloc to
+allocate a buffer ...". However, uClibc doesn't support this functionality and
+issues a warning at compile-time when the function is called with a NULL
+argument.
