Details

Unlike the bundled zlib and libpng, there is no symbol name rewriting done for libjpeg. This causes libxul to export those jpeg symbols which could be incorrectly used by an embedding application and lead to a crash.

As an example, I was getting crashes in galeon when visiting websites using jpeg favicons because the gdkpixbuf jpeg loader ended up using jpeg symbols from libxul instead of the system libjpeg. I worked around it locally by building --with-system-jpeg but the correct thing should be done in the bundled case.
Flags: blocking1.9?
With modern GCC that supports #pragma visibility (which includes all of our trunk compilers) this is not an issue. WFM
