Reader 9.1 (Linux) takes 100% CPU

Question

Initially when starting Adobe Reader and opening a document everything is fine. But after a few minutes Reader takes up to 100% CPU. This also happens when starting Adobe Reader without opening a document.
It's Adobe Reader 9.1 (AdobeReader_enu-9.1.0-1.i486) on Fedora 10 (i386)

Hello there,
I can reproduce the same issue. I just start acroread (without any options or files), wait some time and suddenly acroread starts to use one whole cpu. Here some information about the system:
> cat /etc/issue
CentOS release 5.2 (Final)
> uname -a
Linux wumc0310 2.6.18-92.1.22.el5 #1 SMP Tue Dec 16 11:57:43 EST 2008 x86_64 x86_64 x86_64 GNU/Linux
> acroread -v
9.1.0
I also tried the trick with
> ACRO_DISABLE_FONT_CONFIG=1 acroread
but it didn't change anything.
Do you got some ideas how I can track down this problem? I tried to use
> acroread -DEBUG
but here absolutely nothing happened, just with
> acroread -DEBUG acroread
the reader started and shows
Loading PlugIn /opt/Adobe/Reader9/Reader/intellinux/plug_ins/Annots.api ... [dlopen success for Annots.api, handle = 0xbf32f68]
Loading PlugIn /opt/Adobe/Reader9/Reader/intellinux/plug_ins/EScript.api ... [dlopen success for EScript.api, handle = 0xca14620]
after some minutes the next plugin info occured:
Loading PlugIn /opt/Adobe/Reader9/Reader/intellinux/plug_ins/EFS.api ... [dlopen success for EFS.api, handle = 0xcc1fad0]
and some minutes later, the acroread process started to use the whole cpu...
If I start acroread and try to trace the programm, at first the output looks like:
gettimeofday({1242055601, 629918}, NULL) = 0
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1242055601, 629991}, NULL) = 0
poll([{fd=3, events=POLLIN}, {fd=13, events=POLLOUT}], 2, 15) = 0
gettimeofday({1242055601, 644659}, NULL) = 0
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1242055601, 644729}, NULL) = 0
poll([{fd=3, events=POLLIN}, {fd=13, events=POLLOUT}], 2, 1) = 0
gettimeofday({1242055601, 645655}, NULL) = 0
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1242055601, 645719}, NULL) = 0
poll([{fd=3, events=POLLIN}, {fd=13, events=POLLOUT}], 2, 0) = 0
ioctl(3, FIONREAD, [0])                 = 0
poll([{fd=3, events=POLLIN}, {fd=13, events=POLLOUT}], 2, 0) = 0
and as soon the cpu consumption has started, the output is:
gettimeofday({1242055677, 855078}, NULL) = 0
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1242055677, 855118}, NULL) = 0
poll([{fd=3, events=POLLIN}, {fd=13, events=POLLOUT, revents=POLLERR|POLLHUP}], 2, 5) = 1
gettimeofday({1242055677, 855158}, NULL) = 0
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1242055677, 855197}, NULL) = 0
poll([{fd=3, events=POLLIN}, {fd=13, events=POLLOUT, revents=POLLERR|POLLHUP}], 2, 5) = 1
gettimeofday({1242055677, 855237}, NULL) = 0
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1242055677, 855277}, NULL) = 0
poll([{fd=3, events=POLLIN}, {fd=13, events=POLLOUT, revents=POLLERR|POLLHUP}], 2, 5) = 1
(just for the record)
