Comment 1 Martin Sandsmark 2016-11-20 13:42:48 UTC
Git commit 40b1f0e851c115e1a2df79e7ec4bc4fe726d9e43 by Martin T. H. Sandsmark.
Committed on 20/11/2016 at 13:40.
Pushed by sandsmark into branch 'master'.

Only use foreground process info if valid

getProcessInfo() returned _foregroundProcessInfo without checking the
return value of updateForegroundProcessInfo() indicating whether
_foregroundProcessInfo was non-existent or invalid.

I think this might be the solution to a bunch of recent crash bugs,
but not closing them as I can't test.

Also skipping RB because it is a simple patch and RB is down from here.

Comment 3 tcanabrava 2019-06-24 20:33:45 UTC
sounds fixed already, can you test the new version?
Comment 4 Kurt Hindenburg 2019-07-12 03:24:47 UTC
Reopen if you can duplicate the issue in 19.08 - a lot has changed since 16.08
