RTFM problem:

Two days ago I have written, that I cannot give rights to users or
groups within RTFM.
Error messages:
“System ErrorRights could not be granted for RT::FM::System” or
"System ErrorRights could not be granted for RT::FM::Class".

Installed software: RT 3.0.10 (later than 3.0.5!), RTIR 1.0.0 and RTFM
Environment: Debian Linux, psql 7.3.4

I have found the next messages in the log file:

“Jul 27 07:49:38 cert postgres[18191]: [4] ERROR: pg_atoi: zero-length
Jul 27 09:49:38 cert RT: DBD::Pg::st execute failed: ERROR: pg_atoi:
zero-length string at /usr/share/perl5/DBIx/SearchBuilder/Handle.pm
line 410. (/usr/share/perl5/RT.pm:235)”

I don’t know whether is any connection between log messages and RTFM

Anyone know what I might be missing?
