Trigger Refresh Error - PGAdmin

Hello,
I'm not sure whether this is a PGAdmin bug or otherwise but I was able to replicate on different servers, though I haven't tested it in other versions of pgadmin.

PG Admin v1.14.3
"PostgreSQL 9.1.4 on x86_64-unknown-linux-gnu, compiled by gcc (SUSE Linux) 4.3.4 [gcc-4_3-branch revision 152973], 64-bit"
SLES 11 SP2

To create error:
Right click on trigger object and select refresh.

Error details taken from log:

pgdev pgAdmin III - BrowserERROR: syntax error at or near "AND" at character 527

Please let me know if you require any further details.
