As you can see, the user boinc and all members of the group boinc are allowed to run the apps, but nobody else(except root of cause).
The app_info.xml only needs to be readable for the boinc user, so it does not matter which user copied the file into the folder. Normaly it's readable for everyone(world).

Actually, you're not! :-).
There are three users (apparently) on your machine - perle, boinc and root - even though the three are just one person. No matter how many times you (as perle) enter your password, you don't have permission to even view some files in (some or all of) the boinc owned directories. If you really wish to keep the users perle and boinc separate, but allow perle to access boinc owned files, you (as root) will need to make perle part of the boinc group and change the group permissions on directories to accommodate the incursion of perle into the boinc kingdom :-).
Since doing this requires a bit of understanding of the subtleties of unix file and directory permissions, you might consider whether or not you really need to keep boinc and perle as separate users. Probably the most simple thing is to drop the boinc user and make everything owned by perle. Then you could wander through the boinc kingdom, browsing and editing files whenever you wanted without the restrictions you are currently experiencing.

Which is exactly as expected (excuse the editing to show the filenames more easily). Just do 'sudo ls -l' and you will see the ownership and permissions of all the files. Then do the same in the directory above this one (the projects directory) to see the ownership and permissions of the einstein.phys.uwm.edu directory itself.
This is your problem. Nobody else beside root is allowed to read this file!
sudo chown boinc:boinc app_info.xml
should solve your problems. Enter the command in the folder, where the file exists.
For further information try "man xyz"(without the "), where xyz is the command, where you want to know somthing about, e.g. command options.

[edit]The 4 files that belong to the 4.49 app are owned by root, so you must have installed them as root. But the x-flag(executable) is set for the group(root in this case) and for 'world' too. Because word means everybody, boinc is allowed to execute them too. So this will not lead to problems, but this isn't the best way.
If you are looking for an easy way to handle with rights and ownership, you might install the midnight commander(mc), which imho is a big help for beginners.[/edit]
Now it's clear why you don't run app. 4.49! Wrong permissions!
You and root are not the user, it's boinc. That's the reason your system
