How to repeat:
Clicking around between diagrams and MySQL Model. Will upload backtrace shortly.

Note I used symbols from 5.2.25 to resolve stack. If they are no longer correct, let me know.

Have been able to reproduce this bug also once. Setting verified based on that. Still working on an easy reproducible testcase. Like bug #55776 it has something to do with the "multiple selections" option in "description editor" in "mysql model". For instance: select CTRL-A to select a set of tables in a model, right-click and paste and before the paste finishes (make sure you have enough tables) click on "mysql model" - notice that it now shows "multiple selections" in the "description editor" while being in the wrong tab ("mysql model" instead of "EER diagram"). Combined with some other things, I believe this is where the issue is.

Further analysis of the coredumps from the crash above, based on some findings in other bugs:

-------
0:000> !gle -all
Last error for thread 0:
LastErrorValue: (Win32) 0x6 (6) - The handle is invalid.
LastStatusValue: (NTSTATUS) 0xc0000008 - An invalid HANDLE was specified.
Wow64 TEB status:

Last error for thread 7:

Wow64 TEB status:

I'll add more info on this soon.

I am quite convinced that the following bugs:

bug #55304 | bug #55776 | bug #55904 | bug #55774 | bug #55828

all have the same cause: some sort of issue with window/tab handles (note the "An invalid HANDLE was specified."). 

For more information, see the "[16 Aug 5:30] Roel Van de Paar" comment in bug #55996.

I am marking this bug as a duplicate of bug #55304 as that was the main one in which this issue was handled.
