Bug #65423	Workbench 5.2.40 crahes while I am populating my model

Assigned to:		CPU Architecture:	Any

Description:
It crashes about once in 5 minutes as I am adding inserts to the tables in my model. Seems like it still crashes as I am doing other things, but less frequently. Also, if I save after each 2 new rows, seems ok. The more rows I add without saving, the higher (it seems) the probability of crash once I try to save. Here is what Windows shows in error message:

Tried adding random inserts for more than 5 minutes and got no crash, can you perhaps record a video of you working on the model from start to the point of the crash?

uploaded videos to the support ftp, bug_data_65423.zip

tried to capture full cycle, from start to bug, after installing all optional updates. This time it did not crash, but after a while it would not accept new updates. Even after I pressed "accept updates" button, it would not let me switch to a different table or tab, unless I just closed the tab. But then all new inserts were lost. uploaded capture for_bug_65423_video2.zip

Thanks a lot for your report Vassili.
Reproduced as commented by the reporter.
Windows 7x64
WB 5.2.40

I have experienced this bug as well. I would add that before the crash, I usually find that I cannot get keyboard focus away from the inserts table. Even with the mouse, I cannot switch to my diagram or edit another table, although things like scrollbars and tooltips are function as normal if they're already displayed.

Does this still happen in 5.2.42?

just got 42, did not crash in first few minutes. But then it was intermittent in the past too.

This as fixed as of Workbench 5.2.42, and here's the changelog entry:

  MySQL Workbench would sometimes crash after populating a model.

Thank you for the report.
