Bug Description

Steps to reproduce:

- Launch firefox
- Enter "about:crashcontent" in the URL bar
- Upon hitting return, the tab should crash and display the "This tab just crashed" page
- Ensure that the checkmark to send the crash report is ticked
- Add a comment (anything will do, a non-empty comment ensures that the crash is accepted by Mozilla crash reporting back-end)
- Click on "Restore this tab"
- Go to the "about:crashes" page

Expected behaviour:

In the "about:crashes" page the crash is displayed among the submitted crash reports, showing that the crash report was indeed submitted correctly.

Actual behaviour:

The crash appears among the unsubmitted crashes.

This bug is specific to the packaged version of Firefox that comes with Ubuntu. I've tried reproducing using Mozilla's builds and crash submission works correctly there. See this bug on Mozilla's tracker regarding this behaviour. In Mozilla we noticed the issue because we've started properly processing crash reports coming from Ubuntu and tab crashes were strangely few. Feel free to contact me directly at <email address hidden> about this issue since I'm in charge of Firefox crash reporting machinery.

Thanks for the report Gabriele. I can confirm that the steps in the description lead to an unreported crash. If however I click the "Send" button in about:crashes afterwards, the crash report is correctly sent and processed. Is that what you're seeing too?

Yes, manual submission via about:crashes works fine. It's just the tab crash reporter that doesn't show up as it should.

It appears crashes are not submitted because the minidump-analyzer executable is missing.

Interesting, that shouldn't happen. The minidump-analyzer executable greatly improves our crash telemetry but it's not strictly needed for crash reporting. I'll file a bug on our side to fix that issue.

I built test packages that include the minidump-analyzer executable, and I can confirm that with those crash reports are now submitted as expected.

Gabriele, please share the link to that bug on your side here.
