I am not sure what the data in question are. I would guess png image
This is just a warning, the win32 API sometimes fails to get the GlobalLock
it needs to access the clipboard data, in which case we log this warning and try again. More details in r22796 and #2284.
It seems that this can very easily create noisy output, without any discernable loss of robustness.
Would you consider some nibbling mechanism for this? Like, print it only as a -d clipboard
if it happens less than once per 1-5 seconds (for example)?
