I recompiled libmateweather.so.1.6.9 with 12.04 (Linux Mint Mate13 64-bit):

For Linux Mint Mate 13 users who don't want to wait for an official update, just replace the /usr/lib/x86_64-linux-gnu/libmateweather.so.1.6.9 file. Be sure to make a backup first.
For those who concern the security issue using this patched file or use other Linux distributions, please compile libmateweather.so.1.6.9 from here:
https://github.com/mate-desktop/libmateweather
You may use ./configure --prefix=/usr --enable-shared, then "make" and "sudo make install". It will install libmateweather.* to /usr/lib/. Just move /usr/lib/libmateweather.so.1.6.9 to /usr/lib/x86_64-linux-gnu/ and delete the rest /usr/lib/libmateweather.*
Good luck.
Now I'm happy with my Mate desktop again
