Justin the changes for but 1210188 seem to have caused this issue.  Can you please take a look?

Comment 5

[Justin D'Arcangelo [:justindarc]]

gandalf: any ideas why DurationFormat might cause this?

Comment 6

[Zibi Braniecki [:zbraniecki][:gandalf]]

I have no idea.

I tried to reproduce it and it's very intermittent. I sometimes get it the second time I long-press Home, and sometimes I need 20 long-presses (tested on Nightly from today with Z3).

What's more I can cycle after it happens and everything works again.

No clear errors in the console except of:
E/Music   ( 7021): [JavaScript Error: "uncaught exception: Undefined result for null"]
E/Music   ( 7021): [JavaScript Error: "uncaught exception: Undefined result for null"]
E/Music   ( 7021): [JavaScript Error: "NS_ERROR_ILLEGAL_VALUE: "]

which happens usually before this bug.

Given the intermittent nature I'm really not sure what's going on and I doubt it has anything to do with bug 1210188. I'd guess it may be related to the above JS Error, but it may also be task manager bug or even Gecko's graphic bug.
