I can only produce this on one device running Ubuntu Precise

I have tried to change the content of the library folders with no success.

Running without debugger I get:

Debug [LibraryScanner 1]: Legacy importer took 1 ms
Debug [LibraryScanner 1]: Recursively scanning library.
Fatal [LibraryScanner 1]: ASSERT: "staticMetaObject.cast(_o)" in file lin64_build/library/scanner/moc_scannertask.cc, line 63
Abgebrochen (Speicherabzug geschrieben)

Is it timing related?
