Reports in phpPgAdmin

Hello,

I am trying to set up the reports database with phppgadmin but without
success. I am using the SQL script reports-pgsql.sql. All seems ok (i can
create reports) until I ask for an export. I get:

<br />
<b>Notice</b>: unserialize(): Error at offset 683 of 702 bytes in
<b>/usr/share/phppgadmin/dataexport.php</b> on line <b>118</b><br />
<table class="error" cellpadding="5"><tr><td><p><b>Erreur
SQL :</b><br /></p>
<p><b>In statement:</b><br /></p>
</td></tr></table><br />

<br />
<b>Notice</b>: Undefined property: EOF in
<b>/usr/share/phppgadmin/dataexport.php</b> on line <b>296</b><br />

<br />
<b>Fatal error</b>: Call to undefined function: movenext() in
<b>/usr/share/phppgadmin/dataexport.php</b> on line <b>307</b><br />

I am using PostgreSQL 7.4.7 and phpPgAdmin 3.5.2 packaged by Debian. I
found nothing in the BTS about this.
Thanks for any idea.
