Should not exit on "--browser" use for compatibility reason

Nautilus also works if I open it from the command line, but it does give the following error message:

Gtk-Message: Failed to load module "canberra-gtk-module"

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

there is no stacktrace there

does nautilus work fine for other users? do you have a .local/share/applications/mimeapps.list? does moving it away workaround the issue?

There is no stacktrace because nautilus does not crash. It just doesn't start when opening it from the Places menu or the Cairo dock.

Nautilus seems to work fine for other users. Moving ~/.local/share/applications/mimeapps.list away does nothing to fix the issue.

there is backtrace because that log seems to indicate nautilus is running, could you use "nautilus --quit" then try again to get a stacktrace?

I can try, but as I said before, nautilus works fine if I open it from the command line. The only time it doesn't work is when I try opening it from the Places menu or the Cairo dock. If you still want me to do this, I'll do it tonight and post the results.

ok, thanks for trying but those are still not useful, could you then run it from your dock and use the section for running program of https://wiki.ubuntu.com/Backtrace to get a gdb backtrace (stacktrace != strace, it's done using gdb)

I think this has to do with the following line:

Could not parse arguments: Unknown option --browser

I tried running "nautilus --browser" from the command line and got that same message. But the nautilus man page still lists it as a valid option.

I figured it out. I went through and edited all the nautilus*.desktop files and removed "--browser" from them. Now nautilus launches just fine from both the Places menu and Cairo dock. But that isn't an ideal solution for your average user. If the --browser option isn't going to be used anymore, maybe nautilus could just ignore it, rather than refusing to start.

right, that does seem something we should support for compatibility for custom launchers
