Firefox willl not start in debug mode

[Alfredo Gemma]

Ubuntu 10.4 Beta amd64
Kernel Linux 2.6.32.17-generic
Gnome 2.29.2

After last software update, including new linux kernel, It is not possible to start firefox in the usual way.
Launching Firefox in debug mode (-g option), this following error is displayed:
"/usr/lib/firefox-3.6/firefox": not in executable format: File format not recognized

However, it is possible to launch firefox issuing the command gksu -u root firefox %u in terminal.

Trying to remove and reinstalling does not solve the problem.

You're most likely experiencing bug 518422, so I'm going to change this to be a bug about the debugger not working rather than marking as a duplicate. Bug 518422 should be fixed with an update to 3.6.2 which will be released to Lucid soon. Also, running Firefox as root causes a lot of headaches and is not suggested.

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as Triaged and let them handle it from here. Thanks for taking the time to make Ubuntu better! Please report any other issues you may find.

I've just verified that the problem is solved installing firefox Namoroka/3.6.3pre via daily ppa (ppa:ubuntu-mozilla-daily).

Thank you.
