Not a bug! Exiv2 is not a policeman. You can set any tag to any value. I strongly encourage you to stick to the standard and set GPSVersionID to 4 bytes.
The Exif Specification defines GPSVersionID as a 4 byte tag. Section 4.6.6 p68. http://www.cipa.jp/std/documents/e/DC-008-2012_E.pdf
There is documentation on exiv2.org: http://www.exiv2.org/tags.html
0x0000 0 GPSInfo Exif.GPSInfo.GPSVersionID Byte Indicates the version of <GPSInfoIFD>. The version is given as 18.104.22.168. This tag is mandatory when <GPSInfo> tag is present. (Note: The <GPSVersionID> tag is given in bytes, unlike the <ExifVersion> tag. When the version is 22.214.171.124, the tag value is 02000000.H).
