Can that be fixed in debbugs?  I would love to have both 'git describe'
output as well as commit SHA1 strings be acceptable as version strings.
git describe output starts with v but then contrains fairly much
arbitrary characters as put in the last signed git tag.  SHA1's are
easier, and if the other is a problem then those would still be better
than no version information, I guess.

Thanks,
Ralf
