916617 - since 09-15 nightly, rdio keeps slow-script-dialog'ing

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

Since the 09-15 nightly, playing music on rdio keeps tossing up a slow script dialog roughly every track or so.  It's in some minified script, so that's not useful.  I can't easily capture a profile on this computer at the moment, so filing this bug in case I can do that on another computer, or in case someone else catches anything.

Seems to be triggered often by playing a station, and then expanding out the now-playing view (bottom right button that shows the album covers and stuff).  Often hangs for 10-15 secs when you do that.  Hitting next track often triggers a hang.

Does this also happen with javascript.options.ion.content = false?

Can QA verify reproducibility here - frequency and severity of reproducing would be useful to know as well as the reproducibility of hang.

I have not seen this since upgrading to 09-18 nightly.  This could have been an rdio issue that they fixed, or some other weird issue in the nightlies.. i'll keep an eye on it the next few days and reopen if it reappears.

I'm not able to reproduce this in the latest nor previous Nightly builds. Vlad is this still not reproducible for you? Lukas, if Vlad cannot reproduce any longer I suggest we clear all status and tracking flags.
