<div dir="ltr">Hi all,<div><br></div><div>as a Google Code-In Beginner task students are asked to build Amarok from source. Today we ran into a very strange error a student experienced, which I can't reproduce here, despite using the same distribution (Kubuntu 14.10) and Qt version:</div><div><br></div><div><pre style="color:rgb(0,0,0);word-wrap:break-word;white-space:pre-wrap">[ 10%] Built target amarokshared_automoc
