openni_tracker fails on 12.04
http://answers.ros.org/question/42654/openninite-incompatible-in-fuerteprecise/
According to above, this should been fixed with 1.5.4.0 according to @tfoote but I am still seeing it on Fuerte/Groovy on 12.04.
[ERROR]: Find user generator failed: This operation is invalid!
And I tried the workaround proposed by @pgorczak in there but it no longer works.
Has anyone found another workaround or know how to fix it? Thanks!
