Weird issue with 1.6

Hello,

Thank you again for making Pgadmin Mac Universal binary.

I have strange issue with 1.6 Beta 1 and 2:
Open help, search for any string in "Index" or "Search" tab. It works fine.
Now search for "encode". Pgadmin crashes. Search progress shows that
it found some articles, then it crash when reaches 100%.
It also crashes when you select the word "encode" in index.

Thanks.
