got an error when try to export results to file

[thikor]

1. launch pgadmin3
2. open connection to one of the stored servers
3. open SQL window
4. open file with SQL request
5. F7 => F5 => F8 - type the name of file and try to export
6. got an error (/usr/include/wx-3.0/wx/strvararg.h(456): assert "(argtype & (wxFormatStringSpecifier<T>::value)) == argtype" failed in wxArgNormalizer(): format specifier doesn't match argument type)

an error is very stable. After an error the file has been successfully exported, but it is impossible to export again (empty dialog window)
I have attached an error as screenshot
