Lukas, can you still reproduce it, or was it just one time only exception?
no, I'm not able to reproduce it
I've experienced similar exception - the only difference seems to be, that the missing file was some action in cnd module (Issue #155250), not action in profiler. I worked around it by clean&build of netbeans. There were similar exceptions in the past, always involving some actions - maybe there is some common underlying problem. Can you remember if this was also the case with you (not doing clean before building)?
One-time only exception without any steps to reproduce which was almost certainly not caused by anything profiler related. => worksforme
