Glossary module and 1.6.5 - VERY strange behavior

[possum]

I have installed Glossary and input two term in 'test' category: aaa, bbb.

If I write {cms_module module='Glossary' cat="test" term='aaa'} I have correct result
But when I try to show all category (more than one term):  {cms_module module='Glossary' cat="test"} - the module gives a crash and result page is empty!
If I open dictionary and delete one term (for example 'aaa') - all works fine!
Adding once more term - and problem returns.
Anybody please help! Is this conflict Glossary with 1.6.5 version?
