It depends on the state the above tests left the
memory in.
- Sometimes the png loader tries to report an
"out of memory", but then g_strdup_printf() calls
g_malloc(), which fails.
- There are unchecked realloc()s inside libtiff, which means it
will never work with low memory, unless something drastic is
done, like allocating a lot of memory upfront and release it
before entering libtiff. Also, some TIFFReadRGBAImage calls
returns successfully, even though they have called the error
handler with an 'out of memory' message.
