    Default firefox hangs due to libproxy -> pxgconf

    Hi,

    i have opensuse 11.3 and i am using gnome.

    occasionally my firefox hangs. this is sometimes without any reason i see.
    the only times i can nearly reproduce this, is when i directly open a PDF with evince. in this case a dialog-window opens, asking whether to download or open using evince. if i choose opening directly with evince, evince opens normally. however, then i am unable to close the dialog window of firefox witch makes firefox unuseable.

    when firefox freezes like this, it has a child process called "pxgconf" open (seen in gnome-system-monitor). if i kill this pxgconf, firefox is usable again.

    pxgconf seems to be in /usr/lib/libproxy and thus part of libproxy1-config-gnome-0.4.3-1.3.x86_64 package (i've validated all packages using rpm):

    Code:
    $ rpm -qa | grep libproxy
    python-libproxy-0.4.3-1.5.noarch
    libproxy1-networkmanager-0.4.3-1.3.x86_64
    libproxy1-0.4.3-1.5.x86_64
    libproxy1-config-gnome-0.4.3-1.3.x86_64
    libproxy1-config-kde4-0.4.3-1.3.x86_64
    libproxy1-pacrunner-mozjs-0.4.3-1.3.i586
    libproxy1-networkmanager-32bit-0.4.3-1.3.x86_64
    libproxy1-32bit-0.4.3-1.5.x86_64
    (i don't know how to show package info with rpm, but the package-manager reports they all all from openSUSE-11.3-Oss)

    my repos:

    Code:
    $ zypper lr

    i'm running firefox in thru strace now and directing all output to files, so next freeze hopefully there will be something valuable in there.

    any other suggestions?

    ps: i've already tested this with a new firefox profile, same result.

    Ah. Then I'm not sure what to suggest.

    I also found some strange behavior in firefox that seemed to be at least
    partially related to libproxy1-config-kde4 (under KDE4, not gnome of
    course). I was able to remove this one package (no dependencies). Hence my
    previous question.
