It drives me mad, too.

Another option would be to use Google Code's issue tracker. While it is sort of 
label-based, that's mostly just an illusion of the data entry UI. Labels of the 
form CamelCaseKey-value basically create new key/value metadata pairs, and the 
project admin can control the taxonomy. I believe it comes with a sensible 
default set.

It looks like you can set up Google Code Subversion repo as a read-only mirror 
of the git trunk. This would probably permit the VCS-issue tracker integration.

Both Launchpad's bug tracker and Google Code's issue tracker have Python APIs, 
so perhaps you could migrate the individual issues.
