b) Run google-chrome and try to save a page, it crashes after closing file dialog

Actual Results:

Does this still happen with a recent checkout from master? It could be bug 353080.

Comment 2 Eugene Shalygin 2015-09-25 10:34:53 UTC

It seems to be fixed now, thank you! The crashes are the same, there must be a common source.
