Scratch displays a.out files

If I compile a C++ file with g++ bla.c, the compiler will create the a.out file.

This file shows up in Scratch (unexpected). If I close Scratch and open it back up, the file doesn't show up anymore (expected).

Also if I click the a.out entry, it freezes my editor.

This issue appears to be because the file, when it is first created (before the binary information is written to it), has the content type of a text file.
