Hi,
second time I find a bug in the same function. Here, the function failed
(exception raised and not caught) on a valid PNG file (this image:
https://mega.co.nz/#!W0tXzBAK!iLprbqkVWFAzfcn2GUDRGHiH8Pxyi4DxCQi580shcec).
The error raised by PIL is a `struct.error`, which should be expected but
is not caught by the chunk feeder loop.
The feeder knows this
{{{
except zlib.error as e:
# ignore zlib complaining on truncated stream, just feed
more
# data to parser (ticket #19457).
if e.args[0].startswith("Error -5"):
pass
else:
raise
}}}
but does not know this
{{{
from struct import error
...
except struct.error:
pass
}}}
