1117218 - Stuck at "Loading..." on certain saved profile, throws error "A promise chain failed to handle a rejection."

Status: VERIFIED WORKSFORME

(DevTools :: Performance Tools (Profiler/Timeline), defect)

Description

[Osmose [:osmose, :mkelly]]

Attached is a profile that I saved earlier that would not open in the Profiler. When I tried to load it, the Profiler showed the "Loading..." message and never changed (I could still use the browser, switch to and use other tools, but the profile never loaded).

I generated the profile on Nightly 37.0a1 (2015-01-02), OS X 10.10.1. I tested opening it on the same Nightly with a fresh profile.

Along with the failed loading, I noticed the following error in my Browser Console:

A promise chain failed to handle a rejection. Did you forget to '.catch', or did you forget to 'return'?

Please test again with the new performance tool in Nightly, and reopen if still an issue.

[Victor Porof [:vporof][:vp]]

(the nsIURI.host issue was fixed in a different bug)

Comment 5

[Osmose [:osmose, :mkelly]]

Verified that the attached file no longer stalls on the Loading message in the latest Nightly. Thanks!
