Crash also happens if

1) log into main account
2) log into additional user
3) ctrl-alt-, to go back to main account
4) start crostini
5) ctrl-alt-. to go to additional account

Could you provide crash IDs from chrome://crashes? Thanks!

There are 44 crashes! I believe one relevant one is

1510ff5dfad852c8

but I'm not sure.

Here's another possible relevant

weidongg@: Could you take a look? The magic signature is the same as bug 894583 (ChromeAppListModelUpdater::OnItemUpdated), for which you've landed a speculative fix to 71, but maybe there's more to go on here. Otherwise feel free to mark as a dupe.

I tried the steps in #1 and did not manage to repro the issue. So I think it should be fixed. The issue is also fixed in M71. Do we need to merge back to M70 which still has the issue?

+timloh@ for question in #6

@weidongg yes, please merge back to M70. This looks like a pretty nasty crash and we're asking Googlers (who are the heaviest users of multi-user) to dogfood Crostini. Thanks!

Sure, will do that in the original bug thread.

Experiencing the same.
1. Log in to main account (which has crostini enabled)
2. Log in to additional user
3. ctrl-alt-, to go back to main account
4. Crash, have to reopen all windows
5. Can ctrl-alt-, to go back to alt account w/o crashing but will crash when trying to go back to alt account.

Crash ID: 8c53403bc35f2e03, e174b6cb5c574d5b, and/or f925aac06570b463
