Description:
If you close an SQL Editor Tab that has a Find/Replace dialog box open, subsequently closing the Find/Replace dialog box crashes Workbench.

How to repeat:
- Open a Workbench SQL Editor Tab from an existing script file - or type in new text.
- Open a Find/Replace dialog box associated with this tab.
- Enter a Find string and press Find Next. (Not sure this step is required, but it replicates the scenario I followed.)
- Close the SQL Editor Tab. (Find/Replace dialog box remains open.)
- Then [attempt to] close the Find/Replace dialog box.

This has been fixed as of the soon-to-be-released Workbench 5.2.41, and 
here's the changelog entry:

Closing an SQL Editor tab that had a "Find/Replace" dialog box open, then
subsequently closing the "Find/Replace" dialog box would crash
MySQL Workbench.
