I tried this on Ubuntu Linux 12.04 x86_64 with the most recent 4.3 I-build (I20130319-1000) and I don't see any of these debug messages on the terminal. Which version of EGit are you using? (I have 2.3.1). If you're not on the latest, can you please update and try again?

This was with the latest egit (2.3.1).

Could you perhaps try with the milestone ? - If you see the issue with the milestone but not with the I-Build we can probably consider this fixed. 
If you don't see it with the milestone, check your installed version of webkit:
$ rpm -qa | grep -i webkit

> Could you perhaps try with the milestone ?

I tried with the M6 build now and I still don't see the problem. The webkit version I have is 1.8.3 (webkit for GTK 3). Are you running with GTK 2 or GTK 3? Can you try both and see if there is any difference in behavior?

Comment 4 Martin Oberhuber

As per the RPM output on comment 0 I'm pretty sure I have gtk2 , and I have no idea how I could try this on gtk3.

Anyways this should work on gtk2 too, shouldn't it, so perhaps you should try on gtk2 ?

Comment 5 Arun Thondapu

It does work with GTK 2 for me but I realized that it doesn't really matter which GTK you are running with anyway. The Webkit library that is used is the same for both.

So I'm still not sure why you are seeing these debug messages. It could be something specific in the RHEL version you are using... do you have any other Linux version or distro that you can test with to confirm?

Webkit1 is gone, please reopen this ticket if you experience the issue on 4.8, GTK3.22, and Webkit2.
