I've seen several people mention this, but never been able to reproduce...

Do other sorts of NSPR logging work for you?  If so, is it nsHttp:5 specifically that's broken, or one of the other modules that the http logging page suggests turning on logging for?

Comment 3

[John Daggett (:jtd)]

No, it's all logging, it's not specific to nsHttp.

Seems to be related to something that's no longer in the profile, creating a new profile "solves" the problem.

Comment 4

[Boris Zbarsky [:bzbarsky]]

Hmm.  Can you try to narrow that down to the guilty part of the profile?

Comment 5

[John Daggett (:jtd)]

Zipfile containing copy of profile that exhibits the problem:

Steps to reproduce:

1. Create a new profile 'nullbytes'
2. Options > General > Show my windows and tabs from last time
3. Enter the URL:

http://www.pbs.org/wgbh/pages/frontline/are-we-safer/reporting-the-story/

4. Quit
5. Enable http logging

https://developer.mozilla.org/en/HTTP_Logging

6. Run with 'nullbytes' profile

Result: logfile contains a long string of null bytes

7. Run with 'nullbytes' profile
8. Enter 'www.google.com' in the URL bar
9. Restart the browser

Result: logfile is fine

Not sure what's the cause on that page, maybe embedded Flash?

Yup, setting a  stripped-down test page containing only the <object> tag of the original page causes the problem.

Honza, can you have a look at this? I'm not going to block on this unless this is something that fails in the majority of cases, which it doesn't sounds like this is.

John, this isn't a regression is it, or do we know?

John, could you provide the stripped page as an attachment to this bug please?

Assuming this is caused by bug 534764, it's a regression as of e10s, ie since we shipped OOP plugins.  So not a regression from the last release, but...

[Josh Matthews [:jdm]]

Bug 534764 has never been checked in.

Sorry, meant to say "assumung this is *fixed* by bug 534764"...
