summary: MSN handwritten message crash
discoveredBy: aly89 in ticket #10048 and Elliott Sales de Andrade
The MSN protocol plugin used an incorrect character encoding when attempting to
convert handwritten messages from one encoding to another. This caused the
conversion to fail. This failure combined with an uninitialized variable can
trigger a crash. The only vulnerable versions of libpurple are 2.6.0 and 2.6.1.
Use the correct character set name and initialize error to NULL.
