I honestly don't know. I suppose the app runs fine without the profiler
Can you try with mono trunk? The profiler has received a significant number
of fixes
since the 2.4 release.

I don't like logging:c as it's too heavy-weight to extract any decent
from it.

mono-tools from SVN requires mono from SVN. Not sure if this is the cause of
the compilation problem, but this is our supported combination.  Or did you
use the 2.4.2 mono tools tarball? On this case this has to be fixed.
