Description:
Auto-complete function not working at all on 6.3.4

I have tested older versions too:
6.2.5 -> auto-complete only works for reserved keywords (like SELECT UPDATE FROM) and default functions, like encrypt. Not works on table names or columns.

6.1.7 -> works as expected.

The database i'm accessing is MySQL 5.0.95 running on CentOS 5.

How to repeat:
Be sure auto-complete function is enable on preferences.

Open a new query tab.

(case 1)
Start type "SEL" 
expected that 'popup' with sugestions appears, but nothing happen.

(case 2)
Type "SEL" then press CTRL+SPACE
expected that 'popup' with sugestions appears, but nothing happen.

Thank you for the bug report. I couldn't repeat your issue on Ubuntu 14.04 and Windows: when I type SEL +CTRL+SPACE the pop-up appears with select, also works with F to select the option of from, not problems with databases and tables too.
However it fails with table columns with an error you can see in prior attached screenshot. I could confirm this bug only in this case. Thanks.
