Defunct processes are normal.  They are not a problem.  They are reaped
the next time filterproxy sees any activity.  (i.e. you load another
page)  I initially had written filterproxy to reap these processes
immediately, but due to the non-re-entrancy of signal handlers in linux
and perl, this could cause crashes.  So it's defunct processes or
crashes.  ;)

The 'edit filtering' bookmark seems to work fine for me on this site.
(for the URL http://www.ultimatemetal.com/forum/) I'm using FilterProxy
0.30.

If you get garbage, it may be because the Compress module isn't enabled.
Chances are ultimatemetal.com is sending gzipped pages, and if Compress
isn't enabled then FP can't decompress them.  This also means that the
pages won't be filtered!  This is a common problem.  I've updated some
of the docs to make this more clear.

Ack!  They've made Mason incompatible with filterproxy!  Well the simple
solution is to fall back to the older version.  Hopefully the debian
dependencies are correct and the debian package libhtml-mason-perl will
work.  If not, report a bug against debian.  The package maintainer is

In the next version I'll update FP to work with the new Mason.  Thanks
for pointing this out.
