Doesn't appear to help.
The relevant settings lines are:
In LocalSettings.php (for this wiki):
$wgFileExtensions = array( 'png', 'gif', 'svg', 'jpg', 'jpeg',
'ppt', 'doc', 'pdf', 'xls' );
$wgVerifyMimeType = false;
$wgStrictFileExtensions = false;
$wgCheckFileExtensions = false;
In engineersLocalSettings.php (our own wiki), where I've just switched off PNGs:
#$wgUseImageMagick = true;
#$wgImageMagickConvertCommand = "/usr/bin/convert";
I even did mv /usr/bin/convert /usr/bin/conver2 to make sure it
couldn't use ImageMagick.
Results the same - old PNGs are thumbnailed and re-thumbnailed fine,
new PNGs won't thumbnail at all and warn of possible malicious code.

Any further ideas?
