[Olli Pettay [:smaug][[e-mail]]]

Can this happen even without Fission?
Looks like yes, based on crash-stat this is happening.

[Olli Pettay [:smaug][[e-mail]]]

[Tracking Requested - why for this release]:
Crashes aren't nice.

Comment 3

[Andreas Farre [:farre]]

As Nika said, we hope to alleviate this with bug 1615403. Let's have another look at this bug after that lands.

Comment 4

[Chris Peterson [:cpeterson]]

Nika asked me to assign this bug to her because she is working on MaybeDiscarded bug 1615403.

Tracking for Fission dogfooding (M5) because this is a common Fission crash.

[BugBot [:suhaib / :marco/ :calixte]]

The priority flag is not set for this bug.
:kmag, could you have a look please?

Comment 6

[Pascal Chevrel:pascalc (PTO until April 26)]

Low level of crashes on beta and we are nearing the end of the beta cycle, marking as wontfix for 74.

Comment 7

[Chris Peterson [:cpeterson]]

P3 because crash volume is low. We are still tracking it for Fission dogfooding (M5).

While this crash is not Fission-specific, 29 of 30 crash reports from 75 Nightly had Fission enabled.

Comment 8

[Nika Layzell [:nika] (ni? for response)]

This should be fixed now that bug 1615403 has landed.
