56385 - Weird assertion on startup

Status: VERIFIED DUPLICATE of bug 56505

(Core :: Networking, defect, P3)

Description

[Luke]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)
BuildID:    20001014

I get this popup assertion at startup

###!!! ASSERTION: HTTP cannot send practical requests without this much: '(!mApp
Name.IsEmpty() || !mAppVersion.IsEmpty() || !mAppPlatform.IsEmpty() || !mAppSecu
rity.IsEmpty() || !mAppOSCPU.IsEmpty())', file c:\download\cvs\mozilla\netwerk\p
rotocol\http\src\nsHTTPHandler.cpp, line 1288


Reproducible: Always
Steps to Reproduce:
1. Start up Mozilla
2.
3.

Actual Results:  Mozilla popped up an assertion                            

Expected Results:  Mozilla start up without an assertion                     

Mozilla still appears to report its user agent correctly, 
so the assertion seems invalid.

Reproduced here, Windows 2000, AMD processor.

Comment 2

[Simon Lucy]

After commenting out the assertion and testing each individual component it 
shows all of the tested components to be empty.  As the user agent is reported 
normally later the BuildUserAgent() must be called more than once.

Comment 3

[Simon Lucy]

Actually BuildUserAgent() is called each time a component of the agent is set,
the other occasion is at the end of PrefsChanged() so it looks like it makes no
sense to test the string unless at least one assignment has been made.  The
assertion should be changed to a warning.

I see this too, branch and trunk. Started happening during the day 10/12.

Needs investigationo for RTM. It could indicate a failure to generate the user 
agent string correctly.
