Update, I've found that disabling the 'png' plugin under the 'Image Loading' section "fixes" the issue, at least compiz loads up and runs like it used to. Something must have gone wrong with the libpng-related rebuild. Bug report time?

do

LD_DEBUG=files fusion-icon > log 2>&1

post somewhere the log and then post here the link to see it

Here's the log from a failed run - http://pastebin.com/m6a6cb270

Here's the log from a successful run (with the png plugin turned off) - http://pastebin.com/m62782b96

Both pastebins only available for a month. Interesting line (in my unexperienced opinion) in the first log is line 1914:-      7720:     /usr/lib/compiz/libpng.so: error: symbol lookup error: undefined symbol: png_check_sig (fatal) compiz: symbol lookup error: /usr/lib/compiz/libpng.so: undefined symbol: png_check_sig

It needs to be patched for the new libpng. Open a bug report if there isn't one.

I understand this version IS patched for the new libpng, since it was held in testing just like all the other libpng packages.

FTR: The broken compize-core that was in testing had been rebuilt against the new libpng (it was linking to it) but it still refered to the png_check_sig function which had been replaced in the new libpng. Usually this gives a compilation error but that are edge cases like this one where it doesn't.

http://bugs.archlinux.org/task/18076 is the bug report I just posted.
