Hello list,

I'm trying to profile an application and every time I run fprof:profile() I 
get this error:

> fprof:profile().
Reading trace data...
.....................
=ERROR REPORT==== 28-Jan-2009::18:22:04 ===
Error in process <0.107.0> on node '' with exit value: {badarg,
[{erlang,binary_to_term,[<<0 bytes>>]},{dbg,read_term,3},{dbg,'-mk_reader/2-
fun-0-',2},{dbg,tc_loop,3}]}

{error,{badarg,[{erlang,binary_to_term,[<<>>]},
                {dbg,read_term,3},
                {dbg,'-mk_reader/2-fun-0-',2},
                {dbg,tc_loop,3}]}}


I can run fprof:analyse() afterwards though, and the results don't seem to be 
completely off. Should I ignore this error?

I'm starting fprof in the source of the main routine with fprof:trace(start) 
btw.

thx,
peter.
