Description
Hello all,
I'm having Crash Dumps in current master, on windows 7 64 bits.
After a few tests and some .qgis2 cleaning I realized it has something to do with expression functions created by user.
The attached file causes qgis-master to crash dump when you try to open any expression dialog.
It works well in QGIS 2.8.3 and 2.10.
I was not able to try in Linux
To reproduce copy the attached file to .qgi2/python/expressions folder, open some vector layer and press in select by expression.

I believe this is because that file implements an "area" function, which as of 2.12 is built in and in the reserved name list.
Can you confirm that removing this function fixes the crash?

Nyall, you were right. Renaming the "area" function worked.

I think this still must be considered as a bug.
We anyway should avoid crashes anywhere in the application.
I have been thinking for some solution to fix this and I issued a PR [0].
