Reopen and set the summary to the real cause.
You can already get your thumbnails when ignoring the warnign.

Well it looks like you exchanged working/non working, however both are
pretty fine using HEAD. If you want to verify yourself then doenload
php source and edit ext/exif/exif.c and change the line "#undef
EXIF_DEBUG" into "#define EXIF_DEBUG". Then you'll see all details of
the decoding process.
The test script i used was:
php -r 'file_put_contents($argv[1].".thumb.jpg",
exif_thumbnail($argv[1]));' filename.jpg
and then i looked at the generated file and both are fine.
To Exifer i can only say it seems to correctly rewrite the info as
expected.
If you find an image that really doesn't work of it is specific to
older php versions then feel free to reopen.

Description:
------------
Using the script in the documentation for exif_thumbnail, you can
extract the thumbnail image from the exif-header. If you alter the
exif-information (f.ex. delete the thumbnail and add it again) using
Exifer, the exif_thumbnail function will no longer be able to find the
thumbnail.
According to the author of Exifer, this is likely because
exif_thumbnail doesn't handle offsets to the thumbnail properly.
