The TransformListener needs time to store some transforms so that interpolation can be done. I usually try to create transform listeners as member variables of my class so that they are persistent during runtime. If you are declaring listener as a local variable in a function and then immediately trying to use it then you will get those types of errors.

Edit:
If you want to use the latest transform I suggest using the pcl_ros::transformPointCloud that accepts a target_frame and a tf::TransformListener as opposed to manually converting transforms yourself.
