weird logs when using tab completion on rosrun

edit

Recently, I get some weird log messages when i try to complete the package name (or exec name) for rosrun using the tab key:

rosrun ro[OPTION]...: command not found
PATTERN: command not found
by: command not found
-i: command not found
The program 'and' is currently not installed. You can install it by typing:
sudo apt-get install and

If I enter a fully qualified name rosrun is still working! Also auto completion is still working for roslaunch. Any ideas what could cause this??

Under Ubuntu 14.04.2 ROS indigo....
