Hi Marco,

thanks for your svn fix but get still the same error. 

QIconvCodec::convertToUnicode: using ASCII for conversion, iconv_open failed
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Abgebrochen (core dumped)

Cannot access memory at address 0xb7fb7654

regards,
 Otto
