Well, after a few minutes of doing nothing regarding ROS at all, it apparently finds the package now. Sorry, but I have no idea why it is working after the delay.

However, there is a segmentation fault now:

rosrun my_pcl_tutorial example input:=/narrow_stereo_textured/points2
Segmentation fault (core dumped)

After some research it appears that pointer bugs could be the reason. However, I simply copy-pasted the code in example.cpp from the tutorial. I guess I should make a new question regarding this problem.

Maybe its because I did not download narrow_stereo_textured/points2 into the same folder? I thought it would get the input by itself? I guess I should make a new question regarding this problem.
