Ah sorry I missed that - had you posted it somewhere?

In some cases I have some problems with qgsdebugmsg - the file / func
/ line number is half the reason stdout is so verbose. I tried to get
some key parts e.g. plugin loading to summarise in one line e.g.:

Checking  /home/timlinux/apps/lib/qgis/libogrprovider.so : ... loaded
ok (and with 5 file filters)
Checking  /home/timlinux/apps/lib/qgis/libpggeoprocessingplugin.so :
..invalid (no type)

In other cases the debug messages are showing things that may be
potentially useful when actually debugging but once code is tested and
operational I feel that commenting out or removing is better (do we
really need to know every time a signal / slot connection is made to
the maplayer registry for example). However I guess if we can hideaway
at a higher log level that would be good too.

In general though my feeling is that many of the debug statements
currently in our code are actually better removed and debugging done
with a debugger (I'm as guilty of this as anyone else).

Anyway perhaps we can combine our two cleanups if its not too
difficult to cross merge them...
