[Scoobidiver (away)]

It's currently #9 top crasher in 21.0 with many duplicates.

Comment 2

[Scoobidiver (away)]

It's still #10 top crasher in 21.0 and also #24 in 22.0b1.

Comment 3

[Scoobidiver (away)]

It's #8 crasher in 21.0 and #10 in 22.0b4.

It still occurs in 24.0a1/20130608: bp-bee894ee-185b-40c0-8d95-f98362130609.

Is this a Firefox 20 regression, device regression, or Android version regression?

It seems to happen on ICS and above. It's something that has increased slowly across all channels: #8 in 21.0, #21 at the end of 20.0.1, #37 at the end of 19.0.2. #1 at the end of 22.0?
I think the cache becomes corrupted while it grows

This is not currently a 23.0a2 topcrasher, not tracking.

I disagree. There are 13 crashes (see https://crash-stats.mozilla.com/query/query?product=FennecAndroid&version=FennecAndroid%3A23.0a2&range_value=1&range_unit=weeks&date=06%2F19%2F2013+22%3A13%3A11&query_search=signature&query_type=contains&query=accessing+data+from+it.+at+android.database.CursorWindow.nativeGetString&reason=&build_id=&process_type=any&hang_type=any&do_query=1) so #4 top crasher (see https://crash-stats.mozilla.com/query/query?product=FennecAndroid&version=FennecAndroid%3A23.0a2&range_value=1&range_unit=weeks&date=06%2F19%2F2013+22%3A13%3A11&query_search=signature&query_type=contains&query=&reason=&build_id=&process_type=any&hang_type=any&do_query=1)

See also comment 5 for previous releases.

Comment 8

[Lukas Blakk [:lsblakk] use ?needinfo]

Will wait until it's on Beta to see how it goes.

Comment 9

[Lukas Blakk [:lsblakk] use ?needinfo]

Now that we've shipped beta 1 can we get an update on the volume of this crash?

Comment 10

[Kevin Brosnan [Ex-Mozilla]]

Looking at the top six signatures from comment 0 I still see crashes in 23b1 though the total number of crashes looks to be around 10 - 15 for those six signatures. Is this lower than the 22 cycle (I suspect it is)?

Comment 11

[Scoobidiver (away)]

With every combined signatures, it's #4 top crasher in 22.0, #8 in 23.0b1, and were #14 in 22.0b6 one week ago (Beta and Release populations are different).
If you compare two Betas, it's higher in 23.0 than in 22.0.

Comment 12

[Alex Keybl [:akeybl]]

Adding needsurls and qawanted to start. Next step is to find an engineering owner to take a look at the stack. mfinkle?

Comment 13

[Aaron Train [:aaronmt]]

QA would like to not use qawanted in conjunction with other specific requests (ie steps-wanted or needURLs). I'm not sure how widely that has been announced, but removing that keyword.

Comment 14

[Tracy Walker [:tracy]]

just a few urls from crash stats

Total Count 	URL
8 	about:home
5 	about:blank
3 	about:privatebrowsing
1 	https://addons.mozilla.org/en-US/android/addon/quitnow/?src=api

Comment 15

[Mark Finkle (:mfinkle) (use needinfo?)]

This code is completely rewritten with the new Home page work, scheduled to land in Fx26. Since we have suffered with it this long, I'd rather wait for the new code to land and see what shakes out. The way we are using cursors has changed significantly.

Comment 16

[Lukas Blakk [:lsblakk] use ?needinfo]

Not tracking for 23 then due to comment 15 - we'll wait it out for the re-worked page.

Comment 17

[Kevin Brosnan [Ex-Mozilla]]

Not a top crash in 23 and the about:home rewrite will change this a lot.

Comment 18

[Kevin Brosnan [Ex-Mozilla]]

This went away.

Comment 19

[Chris Peterson [:cpeterson]]

Removing steps-wanted keyword because this bug has been resolved.

Comment 20

[Chris Peterson [:cpeterson]]

Removing steps-wanted keyword because this bug has been resolved.
