Hi, This took me some time to figure out, so I hope this mail will save others some grieve. After installing the glib2 update from todays updates-testing: glib2-2.29.90-1.fc16.x86_64 The following happens: [hans@shalem gspca]$ ldd -r /usr/libexec/e-addressbook-factory linux-vdso.so.1 (0x00007ffffd3c7000) <snip> libfreebl3.so => /lib64/libfreebl3.so (0x0000003c41000000) /usr/bin/ldd: line 118: 5142 Segmentation fault (core dumped) LD_TRACE_LOADED_OBJECTS=1 LD_WARN=yes LD_BIND_NOW=yes LD_LIBRARY_VERSION=$verify_out LD_VERBOSE= "$@" Nasty! Downgrading glibc yields: [hans@shalem watchdog]$ ldd -r /usr/libexec/e-addressbook-factory linux-vdso.so.1 => (0x00007fff2f9ff000) <snip> libfreebl3.so => /lib64/libfreebl3.so (0x0000003c41000000) undefined symbol: g_unix_signal_add_watch_full (/usr/libexec/e-addressbook-factory) Downgrading also glib2 returns the system to working order, maybe only downgrading glib2 is enough, but the seg fault in ldd -r does not look good, so I've downgraded glibc too.
