Bugzilla Bug 210958

gsynaptics, when started, crashes. There was time when gsynaptics worked on my
system, but for some time it doesn't (can't tell when). When installed *not*
from ebuild it works.

There's a patch (no-libgnome-patch) in gsynaptics ebuild which replaces
gnome_pixmap_file() with g_build_filename() (file: main.c, func:
setup_dialog()). When going deeper - crash is inside g_build_filename()
(glib-2.14.6). When looking into g_build_filename() - g_build_path_va() is
called (file: glib/gfileutils.c). Inside g_build_path_va() crash is in line "if
(!*element)", earlier va_arg() doesn't return 0 (end of arguments) but 1, that
causes element to hold invalid address. Perhaps there's something wrong with
g_build_path_va()?

Also there's no icon, but I'm not sure why (probably also cause by the patch).

Temporary solution: install gsynaptics from source, not by using
portage/ebuild.


Reproducible: Always

Steps to Reproduce:
1. Emerge gsynaptics (gsynaptics-0.9.13).
2. Start gsynaptics


Actual Results:  
For a short period of time a window appears, then there's SIGSEGV (Segmentation
fault).

Expected Results:  
gsynaptics is started.

Could you run gsynaptics inside gdb and provide a proper backtrace?

Thanks

Lukasz.

I've just commited 0.9.14 with a fix from the debian folks, it runs here now.
Please reopen if it's not working for you.
