Description:
workbench stops being able to connect to mysql after "yum update"

How to repeat:

workbench was installed using the following commands. Reverse, forward, and sync functions worked perfectly.
- wget http://rpms.famillecollet.com/remi-release-11.rpm
- rpm -Uvh remi-release-11.rpm
- yum --enablerepo=remi install mysql-workbench

Yesterday, I updated the system (yum update). I can still model ER. However, reverse, forward, and sync functions sit there forever when I am at the step to connect to db. "Show Log" button does not show any error.

Here is more info:

- MySQL Query Browser, which is on the same machine with workbench, can connect to mysql fine using the same account. I can query and get records back.

- system info:
/usr/local/src/workbench >> uname -a
Linux saigon 2.6.30.10-105.2.23.fc11.i586 #1 SMP Thu Feb 11 06:51:26 UTC 2010 i686 i686 i386 GNU/Linux

- SELinux is disabled.

- workbench and mysql are on the same machine.

- I searched bug db and can't find any solutions to this.

I uninstalled 5.1.17 version and install 5.1.18 version, which solves the issue. 5.1.18 can be downloaded here: http://dev.mysql.com/downloads/mirror.php?id=377212

So, this is not repeatable with fresh 5.1.18.

Yes, it's not repeatable in 5.1.18.

Hi,

I selected the connection I wanted, clicked the "Next" button. It's supposed to connect to the database so that I can forward engineer or synchronize model, and it did. However, it just sat there forever after couple of times of successfully connecting to the db. When I closed the freezed window, workbench application closed too. This happens for Forward Engineer and Synchronize Model features in both 5.17.17 and 5.17.18 versions. Is this a known issue? I can't find it any where. I currently have about 70 tables on my model?
