I'm consistently getting an error with the following steps:
1) Search string: item
Scope: Toolbox project (from XSource)
Whole word checked
2) After the search, click Filter
3) On Code page of Filter Builder, specify:
=
Within Same Statement
4) Click Apply
Observed: Error
The Code View is also messed up in this case:
Notes: Whether you click Yes or No, the error appears twice and it recurs when you navigate among results. The issue seems to be specifically with filtering on the equal sign. I'm guessing it's an issue in parsing the XML.
