(Firefox :: General, defect)

Description

[Martijn Wargers (dead)]

Attachment: handlerservice.diff

21:12:22     INFO -  System JS : ERROR jar:file:///builds/slave/talos-slave/test/build/application/FirefoxNightlyDebug.app/Contents/MacOS/omni.ja!/components/nsHandlerService.js:891 - NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIProperties.get]

I see these kinds of errors all the time in the tryserver logs in debug builds. 
They are very annoying, because when looking for "ERROR", this thing comes up all the time.
Also seeing it in local debug builds, all the time.

The attached patch makes this error go away, no idea if it's any good, though.

This was also mentioned in bug 449800.

I'm not a peer of this module, so I can't review this code, but it seems ok, as far as it goes.  Nevertheless, there are a bunch of references to this._ds in this file that should be fixed up like this if we can't get the data source.

And it would be better to figure out why this component is being loaded before the nsIDirectoryServiceProvider that provides UMimTyp (either  nsProfileDirServiceProvider or nsXREDirProvider), since that's the real problem.

I think this error has been fixed by bug 1100069.
