The problem happens when both Fisheye and Crucible have a repository and a project with the same key.
Resolution
As a quick workaround, we recommend having the Crucible project prefixed with "CR-". So if your Fisheye repository is YYY, your Crucible project should be CR-YYY to easily distinguish one over the other.
Alternatively, upgrading to Fisheye 2.7.10 or above would also fix this situation.
