I'm glad that the existing warning has been marked for translation.
There's no reason that it couldn't have been before, so I'm glad to see
it added now.

But I'm not sure that the new warning tells the user anything that the
old one didn't. The old warning says "ignoring extra bitmap file: ...",
leading us to believe that another one has already been opened. The new
warning makes the latter part explicit, but I don't think it adds any
new information that wasn't already readily available.

This is out of sync with the warning you added, causing t5310.74 to
fail.

Thanks,
