TEXT value bug in zabbix proxy

[zeds]

I _think_ there is a bug in zabbix proxy related to active checks and TEXT (at least) values.
Zabbix server - version 1.8.3 Linux 2.6
zabbix proxy - version 1.8.3 Solaris 8
zabbix agent - version 1.8.3 Solaris 8

I have client ( Solaris 8 ) monitored by a by a passive zabbix agent checks (CPU etc).
I wanted to add an active check , custom script

#!/bin/perl
my @mas=`/usr/sbin/metastat|/usr/bin/grep State:`;
my $Fail="NO";

foreach(@mas)
 {
 chomp($_);
 s/\s+//g;
#DBG print "$_\n";
 $i=$_;
 if( $i ne "State:Okay" )
  {
  $Fail="YES";
  }
 }

#DBG print "Fail:$Fail\n";
if( $Fail eq "YES" )
 {
 print "FAIL\n";
 exit 1;
 }
 else 
 {
 print "OK\n";
 exit 0;
 }

Script returns TEXT value "OK" or "FAIL" depending on state of metadevices.
So I added a line to zabbix_agentd.conf

UserParameter=solaris.disksuite,/opt/zabbix/bin/disksuite_status.pl

I could see that script runs and sends a value to zabbix_proxy

9052:20100907:125907.548 Before
9052:20100907:125907.548 Run remote command [/opt/zabbix/bin/disksuite_status.pl] Result [2] [OK]...
9052:20100907:125907.549 Sending back [OK]

also I could see that this value is received by proxy

22084:20100907:125907 In add_history(itemid: 29347,key:"solaris.disksuite",value_type:4,TEXT:[OK])
 22084:20100907:125907 In proxy_add_history_text()
 22084:20100907:125907 Query [insert into proxy_history (itemid,clock,value) values (29347,1283853547,'')]
 22084:20100907:125907 End of proxy_add_history

then this value is missing when sent to server as well:

It seems to me ( please don't kick me if I am wrong ) - proxy_add_history_text() , loses a value, because value column in insert statement is empty string.
