We need two things to make this actionable:

1. The music files in question - can we get access to them?
2. A crash report ID

[2] can be found by getting the crash to happen, connecting to wifi, and waiting for the report to be submitted. Upon submission, follow the steps here - https://wiki.mozilla.org/B2G/QA/Tips_And_Tricks#Getting_crashes_off_the_Device to get your crash report ID.

I cannot report crash. It's connected by WIFI and Crash report setting is set to "Always send a report"
However every crashes leaved in minidump directory.

I attached one.

I'm talking about a crash report ID. When you crash, a crash report gets queued to get sent to Socorro. After being connected to wifi, a crash report is then sent to Socorro. After the submission is successful, a crash report ID should appear in the following directory in your phone:

/data/b2g/mozilla/Crash Reports/submitted

What I'm asking for is the latest crash report ID found in this directory after the crash is submitted.

I don't know why crash report is not uploaded.
.dmp and .extra files remained in minidump directory.
They doesn't move to Crash Reports/submitted.

I upload dump file with call stack.

It seems that we have reproduce this crash since the fix landed on the v1.1.  Has the reporter seen the crash with the fix present?

No, after the patch, I have never seen crash by same steps in comment #0.
And same call stack attachment #763997 [details], neither.
