gtk2 applications segmentation fault

Today it seems all gtk2 applications fail to start and just say: "segmentation fault (core dumped)"

doing some debugging the issues seem to be with libgdk-x11-2.0.so.0.2400.31

Everything seemed to be working fine yesterday.  Here are the packages that have been updated since then:

upgraded python2-acme (0.9.0-1 -> 0.9.1-1)]
upgraded certbot (0.9.0-1 -> 0.9.1-1)
upgraded certbot-apache (0.9.0-1 -> 0.9.1-1)
upgraded certbot-nginx (0.9.0-1 -> 0.9.1-1)
upgraded texinfo (6.1-4 -> 6.3-1)
upgraded weechat (1.5-2 -> 1.6-1)
upgraded wine (1.9.19-1 -> 1.9.20-1)
upgraded youtube-dl (2016.10.02-1 -> 2016.10.07-1)
upgraded conky (1.10.4-1 -> 1.10.5-1)
upgraded wpa_supplicant (1:2.5-3 -> 1:2.6-1)

...nothing seems significant.  any ideas would be appreciated, thanks

Re: gtk2 applications segmentation fault

I have a similar problem. Try downgrading libxi to 1.7.6 https://archive.archlinux.org/packages/ … pkg.tar.xz

Re: gtk2 applications segmentation fault

after having some time to do some more debugging, I've isolated the issue to having an xbox 360 controller plugged in.  When I remove the controller, things work fine.  As soon as I plug in the controller, gtk2 applications segfault.  If I remove the controller, no segfault and things work again.

here's an example stack trace from gdb:

#0  0x00007ffff78898ce in ?? () from /usr/lib/libgdk-x11-2.0.so.0
#1  0x00007ffff7864f28 in gdk_display_open () from /usr/lib/libgdk-x11-2.0.so.0
#2  0x00007ffff7834732 in gdk_display_open_default_libgtk_only ()
   from /usr/lib/libgdk-x11-2.0.so.0
#3  0x00007ffff2176275 in gtk_init () from /usr/lib/libgtk-x11-2.0.so.0
#4  0x00007ffff7228f28 in Gtk::Main::init(int*, char***, bool) ()
   from /usr/lib/libgtkmm-2.4.so.1
#5  0x00007ffff7228f8f in Gtk::Main::Main(int&, char**&, bool) ()
   from /usr/lib/libgtkmm-2.4.so.1
#6  0x0000000000412231 in ?? ()

#8  0x0000000000413e69 in ?? ()

xbox controller is using the xpad driver.  This is on a dell xps 13 9343

Re: gtk2 applications segmentation fault

yeah, downgrading libxi seems to fix the issue

Re: gtk2 applications segmentation fault

Then it's certainly the same issue. In my case the offending device was the touchscreen, so blacklisting the 'wacom' module provided a temporary workaround.
Thanks for opening the bug report.
