1013945 - Uncaught exception in task: `gThreadClient is null`

Status: RESOLVED FIXED

(DevTools :: Debugger, defect, P2)

Description

[James Long (:jlongster)]

I'm almost positive this error existed before the Task.jsm port (I've seen it before), but Task is now reporting it consistently. It looks like it happens when a test is shutting down. One test that triggers it is browser_dbg_auto-pretty-print-02.js, but others do too.

In the browser_dbg_clean-exit.js test, the error is `this.activeThread is null` instead, but seems to happen at the same time (when the test is shutting down).
