I understand devnulling stderr isn't best option, but seriously if,
simple php script which just outputs a single number is broken, then I
think all other php script in the system will not work or output same
warnings, and it will be quite easy to notice this problem. So
devnulling stderr in cron job isn't actually hidning anything IMHO.

Interesingly I almost everytime add --purge to my dist-upgrade or
remove, so it should be purged, with configuration files.

$ dpkg -l | grep php | grep -v ^i
$ 

Whatever was reason configuration files are still there, I assume it is
just history. (I think i installed php_gtk2 or cairo using pear or just
manually compiling, when trying to run phoronix-test-suite before it was
in Debian repos. But I think it wasn't the case with sqlite extension,
which in fact was almost always in Debian for long time).

I just manually removed offending ini files in /etc/php5/conf.d, and it
should not make any more problems for me.

(btw. I really like new conf.d structure).
