When I run any query (or an edit of a table data) that involves returning columns defined as text, they are all being returned instead with a blob icon and there is no way to see the contents of the column.  Prior to upgrading to this version, all text fields returned their actual text instead of showing blob.

How to repeat:
Query or edit a table that contains a text field.

Suggested fix:
Display the contents of the text field instead of the blob icon.  I would also recommend that there be some way to display the content of blob's similar to QB, however that should go to a new bug.

In #50111 MySQL developer Sergei Tkachenko already reported that all kind of text fields are represented as BLOB values to avoid ui performance hit caused
by potentially large values. However, would at be at least possible to add an option that enables the output of text fields (at the risk of performance degradation)? Text fields are so common today that I doubt most users like the current behaviour.

I will work on adding such an option. The idea is to provide global WB option specifying number of symbols to represent for TINYTEXT/TEXT/MEDIUMTEXT/LONGTEXT fields, and the rest of the field value will be truncated until you start editing. Default value for the option will be 256. To disable truncation when visualizing field values in grid you'll have to set it to -1.
Any objections?

I think that the solution described by Sergei would be excellent and a most-welcome improvement.

Such an option would be great! Can you guess how long it will take you to implement this feature?
[29 Jan 2010 16:10] Sergei Tkachenko
v5.2.16 will most probably contain the fix. At least it's planned to be so.

A restart is required after changing the byte size to -1, just FYI to save you 5 minutes. ;p
