Bug #46304	Unhandled glibmm exception results in forced exit
Submitted:	20 Jul 2009 11:44	Modified:	4 Sep 2009 10:16
Reporter:	Craig Fowler	Email Updates:
Status:	Closed	Impact on me:	None
Category:	MySQL Workbench	Severity:	S3 (Non-critical)
Version:	5.1.17	OS:	Linux (Kubuntu Jaunty using (new Ubuntu 9.04) .deb installer - 32 bit)
Assigned to:		CPU Architecture:	Any

Description:
I discovered this one somewhat by accident.  Workbench forcibly closes due to an unhandled glibmm exception if the mousewheel is used to switch between tabs in the properties pane.  STDOUT output will be attached.

How to repeat:
Open or create a new model, add a table to the model and then double-click that table so it's properties pane shows at the bottom of the model.

Mouse-over the tab bar at the bottom (Tables, Columns, Indexes etc) and use the mousewheel (which has the effect of switching tabs).

Workbench switches tabs, then a split-second later it closes without saving.

STDOUT created when this bug is reproduced

I couldn't repeat the behavior reported on Ubuntu 9.04 64-bit.

Probably worth saying I'm using x86 then ;)

Hello Craig,

I have ubuntu jaunty (9.04) 32bit here. But I wasn't able to reproduce it. Scrolling with mouse wheel works fine here.

It looks like that it is really Kubuntu related.

Anyway, for deeper analysis we would need the core dump.

Hi, would like to confim that this bug also affects 5.1.17 but I also noticed that I missed out some information in "how to reproduce" the bug, namely I can't get WB to crash on the 'first open' of the table-edit pane.

So - to revise my "how to reproduce" instructions:

1) Open WB and create a new project
2) Add a new table to that project (either by creating it in the project main view or by creating a new ER diagram and adding the table visually).
3) Edit that table and accept the default name (`table1` in my case)
4) Go to the columns tab and accept the name of the first column (`table1_id` in my case)
5) Close the edit pane for table1
6) Re-open the edit pane by double-clicking the table in either the diagram or in the list of tables
7) Use the mousewheel to scroll through the tabs Table/Columns/Indexes

The crash occurs at this point.  Without closing and re-opening the table-edit pane I discovered that I can't reproduce it either.

Verified following instructions in the reporter's last comment on Ubuntu 9.04 64-bit and 5.1.17.
