unable to run current CVS [_IO_*/__flockfile, __pthread_waitfor_restart_signal]

[Josh Sled]

I've been unable to run CVS for a few weeks, now ... 

The general symptom is...

#0  0x400f2966 in __sigsuspend (set=0xbfffe380)
    at ../sysdeps/unix/sysv/linux/sigsuspend.c:45
#1  0x40d84d61 in __pthread_wait_for_restart_signal (self=0x40d8e460)
    at pthread.c:969
#2  0x40d86aa3 in __pthread_alt_lock (lock=0x81d8048, self=0x0) at restart.h:34
#3  0x40d82fb6 in __pthread_mutex_lock (mutex=0x81d8038) at mutex.c:120
#4  0x40d85d8b in __flockfile (stream=0x81d7fa0) at lockfile.c:39
#5  0x4013c9c5 in _IO_link_in (fp=0x81d7fa0) at genops.c:108
#6  0x4013c5f9 in _IO_new_file_init (fp=0x81d7fa0) at fileops.c:150
#7  0x401322af in _IO_new_fopen (
    filename=0xbfffe590 "/usr/lib/python1.5/site.pyc", mode=0x409780d2 "rb")
    at iofopen.c:63

... though frames above #4 change in ea. occurance [frames 0..4 are
consistent].

I noticed it first with attempting to load the modular libraries; going
from libtool1.4b to libtool-1.4.2 seems to have fixed this.

Then, I was getting it on attempting to load
/usr/share/pixmaps/gnome-term-tiger.png [gnome_window_icon_init -> ... ->
gdk_imlib_load_image] ... removing this file sidesteps that error,
which then lets me see the above backtrace, occuring on attempting to
load site.pyc [for Guppi init].

Any clues/help?
