Bug with decimals

[zanknaf]

When there is an approval transaction sometimes this bug occurs with decimal conversion to int.

Example transaction:
0xf1591d5457cc44e71f5e6fa29f90e71d2ffab953a1aefccbe0e3678936650635

Error simulating transaction: invalid literal for int() with base 10: '0xf2a2aacfbf73995f9c1a944a804692857cc83260'

Probably fixed, need testing
