Description Lukasz Goralczyk 2008-02-21 11:32:13 UTC

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

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.
