Hi everyone,
looks like upstream fixed this already [0]. The fix is easily imported
into packaging, see attached debdiff.
I would be happy to NMU this within a week or so if there is no action
by the maintainer to avoid mysql++ to be removed from testing. Please
let me know if this is not wanted. Also addressing this mail to the
previous uploader of the package.
mysql++ is a dependency of my augustus package, which I would prefer not
to be removed from testing.
Thanks
Sascha
