-current firefox (52.1.2esr) gtk/gdk segfault

TommyC7 · 05-26-2017, 12:23 PM

Hello all,

I'm getting a segfault with firefox 52.1.2esr on -current and was wondering if anybody else has been getting it.

To reproduce:

1) Open firefox
2) Attempt to open a new tab by double clicking on the tab bar

And then I get this error from gtk:

Code:

**
Gdk:ERROR:gdkwindow-x11.c:5165:create_moveresize_window: assertion failed: (mv_resize->moveresize_emulation_window == NULL)
Redirecting call to abort() to mozalloc_abort

zsh: segmentation fault  firefox

Couple of notes:

1) gtk+2 is the package that provides the create_moveresize_window function.
2) The actual line is not 5165 in the gtk's source code for gdkwindow-x11.c but a little down below, but the function is still quite small and occurs as the g_assert() so looking for it should be enough.

I tried to find where in the source code of firefox it uses create_moveresize_window to no avail (I tried with `find <path to source> -type f -exec grep "create_moveresize_window" {} +').

I'm wondering if anybody else has run into this?

Cheers.

Hello,

Looks like this.

Hmmm...

So I'm assuming that means firefox was built with gtk+3 then?

I'm wondering if rebuilding it with gtk+2 would fix this as the bug report states.

Hello all.

I'm just bumping to ask again if anybody actually gets a segfault doing the same thing as I did or if it's just me.

Cheers.

latest slackware64-current up-to-date, firefox started with a clean profile: if I doubleclick with the left mouse button on the firefox tab bar nothing happens, if I click with the middle button on it a new tab opens.

Cheer, I'll try to find out why my firefox happens to be doing this.

I think I'll try to rebuild linking against gtk+2 specifically instead of gtk+3 and see if that helps.

I could have sworn though that double clicking on the tab bar used to open a new tab (the middle click one works for me as well for what it's worth).

I know it used to do this, but it seems it may not anymore. To test, I downloaded the latest version on my Windows computer and installed it, and double-click on the tab bar now just maximizes or "Restores down" (as Windows calls it) the window. So, this looks to be a deliberate change for Firefox, at least on Windows.

I did a quick search, and it seems if you toggle browser.tabs.drawInTitlebar to false in about:config, which will take the tabs out of the title bar and into their own row, it will then restore the double-click to open a new tab feature. I don't have easy access to a Slackware computer running X to test if this is the case in Linux.

I don't think GTK+2 version supports drawing tabs in titlebar, this is GTK+3 and GNOME specific, it's one of the reasons why GNOME is listed as recommended dependency on mozilla website.
Anyway, it works "doubleclick opens new tab" on browser compiled with GTK+2 but the option browser.tabs.drawInTitlebar doesn't appear to do anything.
