This is a known issue  with an external library (zlib). We opted not to include the valgrind suppressions in the dovecot source.
To silence the error, execute the following in the top direcotory of dovecot source:
cat << EOF > ./run-test-valgrind.supp
{
   <squeezy-zlib-uninitialized>
   Memcheck:Cond
   fun:inflateReset2
   fun:inflateInit2_
   fun:i_stream_zlib_init
   fun:i_stream_create_zlib
   fun:test_compression_handler
   fun:test_compression
   fun:test_run_funcs
   fun:test_run
   fun:main
}
EOF

We use this on squeezy, but i think the call stack should be the same.
