Comment # 5 on bug 774629 from Tim-Philipp Müller
I think we should be making use of the new _WITH_DETAILS API for
error/warning/info messages here, since the error code itself is really quite
meaningless and the app can't rely on the error string (might be translated in
future) or the debug string (should not be looked at).
Or add a new error code for it.
Or use a different kind of message (maybe progress messages?)
