The problem happens intermittently

Error log.

Workbench crashes when changing the referenced table in the foreign keys of many tables.

I am changing the referenced table in many tables... One after the other... In some cases Workbench crashes

Please, send the output of:

uname -a
cat /etc/issue 

Linux commands.

uname -a:

Linux mdarkstar 2.6.33.4 #3 SMP Tue Sep 21 17:42:09 CDT 2010 x86_64 Intel(R) Core(TM) i7 CPU       Q 840  @ 1.87GHz GenuineIntel GNU/Linux

cat /etc/issue:

Welcome to \s \r (\l)

Please, send URL you had used to download Workbench binaries. Or you built it from source?

I build it from source.

The errors are consistent when I move between tables while having the "Table properties tab opened (The one that has: Table, Columns, Indexes, etc.)" If this tab is opened and I switch between tables to change Foreign Key information the software crashes at random. The same does not happen if I close the tab before using another table.

Thanks a lot for your report Carlos.
Can you please provide us with a sample (.mwb file) of a Model where you can reproduce this defect?
Thanks.

Hi, 

Thanks for your support.

I just uploaded the model. To test it, please change foreign keys among different tables WITHOUT closing the "table properties tab". Eventually after some time changing this... WB crashes.

Carlos.

Thanks for the info Carlos.
2 things:
- Are you doing the changes in the Foreign keys in the model or one of the diagrams?
- Are you using the "Edit in new window" option?
- Can you please paste here the output that you get from "Help -> System Info"?
Thanks.

I am doing changes in foreign keys in both the model and diagrams. Eventually crashes in both.

I am doing double-click in a table to open its properties and change values. The crash happens when I change something then double click in another table  change something, double click in another table and so on...eventually WB crashes. However, if I close the "Properties tab" before double-clicking in another table WB does not crash.

System info is:

MySQL Workbench CE for Linux/Unix version 5.2.34

Data Directory: /usr/local/share/mysql-workbench
Cairo Version: 1.10.0

CPU: 8x Intel(R) Core(TM) i7 CPU       Q 840  @ 1.87GHz 1199.000 MHz, 3.8 GB RAM

It's happening exacly the same thing with me. Sometimes just connecting to my local database segfaults. After that, on the SQL Editor only if I "Alter Table..." by right clicking. On the EER Diagram happens constantly, but I never tried to close the tab everytime I change table.

Here is my info:

$ uname -a

I'll attach a dump as well.

Hope it helps

Thanks a lot for your report Carlos.

Fixed as of 5.2.38:

Selecting and editing multiple indexes or foreign keys would
crash Workbench.
