Firefox 3.0.3 on OpenSolaris Build 99 dumps core during printing with automatic printer discovery

After getting the printers back with the automatic printer discovery in the
service
svc:/network/device-discovery/printers:snmp

They are also listed in the print-Menu of firefox 3.0.3. But Firefox hangs and
a pstack on the process shows a SIGSEGV.

I found a printing solution in the following mailing thread.

For solving the problem it suggests to LD_PRELOAD the libc.so library.

So I inserted into the firefox-Script at the beginning:

LD_PRELOAD=/usr/lib/libc.so
export LD_PRELOAD


After restarting firefox printing worked again.
