Zac - Do you know what STR you used to hit this crash?

Comment 2

[Zac C (:zac)]

I was running test automation and happened to catch the device with the crash submission dialogue open so cancelled the test and submitted the crash. 

I couldn't say what caused it but I wanted to log it for posterity.

Caught this today by running a single Gaia UI unittest - test_connect_to_local_area_network[1]

Here's the crash report: https://crash-stats.mozilla.com/report/index/f012238b-c3ad-4d6a-a311-7278c2140812

Alison, would you please help the developers run this test on master until you/they can reproduce the failure?  Thanks!

I'll look into first.

Comment 7

[Yoshi Cheng-Hao Huang [:allstars.chh][:allstarschh][:yoshi]]

I've run several times but didn't meet the crash.
Also It seems Stephen uses an older version of nfcd.

I've confirmed that we're running the V123+fonts base/vendor build, so not sure how/why nfcd is out of date.

Thomas, do you know why we might be on an older version of nfcd, despite being on the latest vendor base build of V123+fonts?

No, no idea. The latest version should always be in the branch 'master'. Dimi, do you know about any exceptions?

If you are using vendor's build as base image, then the nfcd may be older one because they don't keep updating nfcd to latest build.

All of QA team is synchronised onto the same public base build.

[Cody Roesch [:croesch]]

I just hit this crash, while hunting another crash. Below are my variables and some STR's I was doing.

STR:
1. Launch Video app.
2. Start playing a video
3. Tap the home button to put it into the background.
4. Hold the Home button and quickly tap Restart until the phone restart happens.

Tried to reproduce this about 20 times with no luck.
1/20

[Yoshi Cheng-Hao Huang [:allstars.chh][:allstarschh][:yoshi]]

[Blocking Requested - why for this release]:
Request for nominate to 2.1+ as this should be regression from Bug 933588.

Comment 15

[Wesley Huang [:wesley_huang] (EPM) (NI me)]

triage: regression, crash

Comment 16

[Adam Alldredge [:AdamA][Inactive]]

I just hit this crash while working on the test pass.

Prerequisite: have 2 devices with NFC enabled.

Repro Steps:
1) Update a Flame device to BuildID: 20140827040203
2) Open an item that can be shared through NFC on one of the phones
3) Move devices back to back so that "Swipe to share" appears
4) Pull devices apart so they return to normal
5) Repeat steps 3-4 at least 4 times
6) Observe one or both devices crashing

Repro Rate: 11/12

Notes:
It is not always the same device that will crash but one of the devices will almost always crash following these steps.

[Derek Harris [:DerekH] - Dont need info. Last day 6/5/15]

Removing regression window wanted, did not realize the window was already found

Comment 18

[Marcia Knous [:marcia]]

I hit this crash 2x today - once when I was actually on an active phone call. I hope this gets fixed soon.

Comment 19

[Yoshi Cheng-Hao Huang [:allstars.chh][:allstarschh][:yoshi]]

Firmware v122 and v123 uses older nfcd, which will send fragmented data.
The master branch of nfcd already fixes this.
