I've installed Private Joe and Lord of Ultima, and when I start either from a terminal I see this message.  Lord of Ultima goes on to run OK despite the "CRITICAL".

Using strace, this warning prints after lstat("/home/skierpage/programs/firefox/webapprt". Both my firefox (nightly profiling) and webapprt-stub are 64-bit.

FWIW bug 672671 is the same warning from elsewhere in the codebase, with a fix.

lstat("/home/john/bin/firefox-nightly/firefox", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
open("/usr/lib/x86_64-linux-gnu/charset.alias", O_RDONLY) = -1 ENOENT (No such file or directory)
write(2, "\n(webapprt-stub:22023): GLib-CRI"..., 100
(webapprt-stub:22023): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed
) = 100

For me its triggering once XRE_main is called, the last lstat is from XRE_GetFileFromPath(firefoxDir).
If an error dialog isn’t needed in normal use case, gtk doesn’t need to be inited. So I moved that into the ErrorDialog function and it no longer triggers the assert ‐ XRE_Main expects nothing gtk/glib inited beforehand.

Attached patch Same patch with arguments (obsolete) — Splinter Review
Thanks John.
I don't know if we can do something like this, because we should call gtk_init (or gtk_parse_args) in the main function (because we want gtk to remove its arguments from argc and argv).

CC'ing Glandium to take a look here, as the comments from the similar bug 672671 say that this error makes jemalloc not work, and he might now what is the proper way to fix it.
I could add a function to remove the gtk related arguments if this assertion is important (this would be a better solution than the other patch, but would complicate the webapprt code a bit).

XRE_main calls gtk_init already, and I think that's the main reason why you can't call gtk_init before.

I don't think this has any effect on jemalloc. The assertion probably "simply" comes from the double gtk initialization.

After checking, this comes from g_slice_set_config (in XRE_main) being called after gtk_init (in main).

The error doesn't have an effect on jemalloc, however, it has an effect on gslice memory allocation using its own slab allocator, which may increase memory fragmentation, and thus firefox memory usage.

Indeed the simple double initialization isn't a problem for gtk (they don't do anything on the second initialization).

Set gslice only when needed

I preferred the patch that moves gtk initialization into the error function.

With that method we won't support GTK commandline options. Don't we care about them?

Why wouldn't we, since XRE_main does handle them?

Same patch with arguments

Oh, you're right! I couldn't find gtk_parse_args with MXR because I was searching for an identifier (and MXR, I don't know why, doesn't handle it as an identifier).

Same patch with arguments

>+  gtk_init(pargc,pargv);

File style is to have spaces between parameters.

This approach also saves having 2 connections to the X11 display.
Fortunately gdk_set_program_class doesn't need a g_type_init.
