I am seeing the same problem everytime I click a download link (lins that you can't right click and do same as e.g Firefox download link http://en.www.mozilla.com/products/download.html?product=firefox-2.0.0.6&os=linux&lang=en-US ) will consistently crash Firefox. When Firefox is run from the terminal the following messages are displayed semakwetu@kompyuta:~$ firefox OpenOffice path is '/usr/lib/openoffice' *** glibc detected *** /usr/lib/firefox/firefox-bin: munmap_chunk(): invalid pointer: 0x08b2f520 *** ======= Backtrace: ========= /lib/tls/i686/cmov/libc.so.6(cfree+0x1bb)[0xb76fd93b] /usr/lib/libglib-2.0.so.0(g_free+0x31)[0xb750c8c1] /usr/lib/firefox/components/libgfx_gtk.so[0xb643bc56] /usr/lib/firefox/components/libgfx_gtk.so[0xb645b259] /usr/lib/firefox/components/libgklayout.so[0xb6c4c23d] /usr/lib/firefox/components/libgklayout.so[0xb6c4cfc7] /usr/lib/firefox/components/libgklayout.so[0xb6c930ab] /usr/lib/firefox/components/libgklayout.so[0xb6da48f1] /usr/lib/firefox/components/libgklayout.so[0xb6da4760] /usr/lib/firefox/components/libgklayout.so[0xb6da55ab] /usr/lib/firefox/components/libgklayout.so[0xb6da4855] /usr/lib/firefox/components/libgklayout.so[0xb6c65825] /usr/lib/firefox/components/libgklayout.so[0xb6f44cd5] /usr/lib/firefox/components/libgklayout.so[0xb6f478a9] /usr/lib/firefox/components/libgklayout.so[0xb6f4dcf0] /usr/lib/firefox/components/libgklayout.so[0xb6f4fdb9] /usr/lib/firefox/components/libgklayout.so[0xb6f50bd8] /usr/lib/firefox/components/libgklayout.so[0xb6f449d6] /usr/lib/firefox/components/libwidget_gtk2.so[0xb62532ee] /usr/lib/firefox/components/libwidget_gtk2.so[0xb624af92] /usr/lib/firefox/components/libwidget_gtk2.so[0xb624b01b] /usr/lib/libgtk-x11-2.0.so.0[0xb7bb9b62] /usr/lib/libgobject-2.0.so.0(g_closure_invoke+0x122)[0xb75a2772] /usr/lib/libgobject-2.0.so.0[0xb75b32fd] /usr/lib/libgobject-2.0.so.0(g_signal_emit_valist+0x68f)[0xb75b45cf] /usr/lib/libgobject-2.0.so.0(g_signal_emit+0x29)[0xb75b49c9] /usr/lib/libgtk-x11-2.0.so.0[0xb7cf3118] /usr/lib/libgtk-x11-2.0.so.0(gtk_main_do_event+0x42f)[0xb7bb2eaf] /usr/lib/libgdk-x11-2.0.so.0[0xb79ec831] /usr/lib/libgdk-x11-2.0.so.0(gdk_window_process_all_updates+0x97)[0xb79eca57] /usr/lib/libgtk-x11-2.0.so.0[0xb7b08b7d] /usr/lib/libgdk-x11-2.0.so.0[0xb79d2a48] /usr/lib/libglib-2.0.so.0[0xb7503551] /usr/lib/libglib-2.0.so.0(g_main_context_dispatch+0x17c)[0xb750511c] /usr/lib/libglib-2.0.so.0[0xb750855f] /usr/lib/libglib-2.0.so.0(g_main_loop_run+0x1a9)[0xb7508909] /usr/lib/libgtk-x11-2.0.so.0(gtk_main+0xb4)[0xb7bb32d4] /usr/lib/firefox/components/libwidget_gtk2.so[0xb6251bd2] /usr/lib/firefox/components/libtoolkitcomps.so[0xb619bde2] /usr/lib/firefox/firefox-bin[0x804ea79] /usr/lib/firefox/firefox-bin[0x804ab8f] /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe0)[0xb76a6050] /usr/lib/firefox/firefox-bin[0x804aae1] ======= Memory map: ======== 08048000-0805b000 r-xp 00000000 03:01 2343257 /usr/lib/firefox/firefox-bin 0805b000-0805d000 rw-p 00012000 03:01 2343257 /usr/lib/firefox/firefox-bin 0805d000-091e7000 rw-p 0805d000 00:00 0 [heap] ac7c5000-acab2000 r--p 00000000 03:01 2572314 /usr/share/fonts/truetype/baekmuk/dotum.ttf acab2000-adb7f000 r--p 00000000 03:01 2572311 /usr/share/fonts/truetype/arphic/ukai.ttf adb7f000-ae2e9000 r--p 00000000 03:01 2572329 /usr/share/fonts/truetype/kochi/kochi-gothic-subst.ttf ae2e9000-ae36d000 r--p 00000000 03:01 2588908 /usr/share/fonts/truetype/ttf-dejavu/DejaVuSans-Bold.ttf ae467000-ae473000 r-xp 00000000 03:01 2736505 /usr/lib/gnome-vfs-2.0/modules/libfile.so ae473000-ae474000 rw-p 0000b000 03:01 2736505 /usr/lib/gnome-vfs-2.0/modules/libfile.so ae474000-ae500000 r--p 00000000 03:01 2588907 /usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf ae500000-ae521000 rw-p ae500000 00:00 0 ae521000-ae600000 ---p ae521000 00:00 0 ae645000-ae64c000 r-xp 00000000 03:01 2329024 /usr/lib/libfam.so.0.0.0 ae64c000-ae64d000 rw-p 00006000 03:01 2329024 /usr/lib/libfam.so.0.0.0 ae64d000-ae653000 r-xp 00000000 03:01 7438362 /lib/libacl.so.1.1.0 ae653000-ae654000 rw-p 00005000 03:01 7438362 /lib/libacl.so.1.1.0 ae654000-ae657000 r-xp 00000000 03:01 7438368 /lib/libattr.so.1.1.0 ae657000-ae658000 rw-p 00002000 03:01 7438368 /lib/libattr.so.1.1.0 ae665000-ae66a000 r--p 00000000 03:01 2655355 /usr/share/locale-langpack/en_GB/LC_MESSAGES/file-roller.mo ae66a000-ae66c000 r-xp 00000000 03:01 2443581 /usr/lib/pango/1.6.0/modules/pango-hangul-fc.so ae66c000-ae66d000 rw-p 00001000 03:01 2443581 /usr/lib/pango/1.6.0/modules/pango-hangul-fc.so ae66d000-ae670000 rAborted (core dumped)
