Description Carlos Garcia Campos 2010-10-28 07:06:57 PDT
In TextEncoding::encode() we need to convert the utf16 input string to utf8 to normalize it using g_utf8_normalize(). We are assuming that the conversion always work, but when it fails g_utf8_normalize() crashes due to NULL pointer. It's reproducible with some of the fast/url tests:

Testing 20 test cases.
fast/url .
fast/url/anchor.html -> crashed
fast/url/host.html -> failed
fast/url/query.html -> crashed
fast/url/standard-url.html -> crashed
0.96s total testing time

16 test cases (80%) succeeded
1 test case (5%) had incorrect layout
3 test cases (15%) crashed
Starting webkit launcher.

Patch to fix the crash

When utf8 conversion fails, just try with the original string
