locale::facet::_S_create_c_locale name not valid

[Anonymous]

When I run ClamAV with the C agent compiled in, I get an error:

$ terminate called after throwing an instance of 'std::runtime_error'
  what():  locale::facet::_S_create_c_locale name not valid
^C
[1]+  Exit 134                sudo .libs/clamd

In case it helps:
