Bug 36530 – Web Inspector: Error when highlighting JavaScript with an invalid mime type

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

[Alexander Pavlov (apavlov)]

- Bring up WebInspector on http://code.google.com/p/chromium/issues/list
- Open kibbles-1.3.1-comp.js in the Scripts panel
- Inspect the WebInspector

On Chromium, the console says that there was an attempt to read the property "lexCondition" of undefined in WebInspector.SourceTokenizer.prototype.getLexCondition()

The js-file mime type is reported as "application/empty" which causes the default parser to be used, even though the parsing has not been set up properly for that.

+ if (resource.mimeTypeIsConsistentWithType())

If this thing returns true, we still might end up with no tokenizer. Should this code be moved to the SourceTokenizer where you could handle this case?
