Steps to reproduce: 1. Create a Toaster project with release master 2. Build busybox 3. When the build finishes, in the build form type: "busybox:clean" then click "build" Result: while the build is in progress, the build target shows correctly as "busybox:clean". But one the build completes, it shows the following as targets: busybox:clean busybox:clean:do_build This is not correct: the build target should be just busybox:clean.
It's a bug in bitbake code, so I've sent fix directly to bitbake-devel: http://lists.openembedded.org/pipermail/bitbake-devel/2016-September/008010.html
The fix has been merged to poky master: https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=5414b80e8df11188d8e67a37185305c34ea084bd
