>Description:
pango 1.28.3 doesn't like certain fonts (Cyberbit, Minion Pro, Myriad Pro...). 1.24.4 works fine.
This affects firefox and other apps.
Backtrace isn't too useful:

>How-To-Repeat:
Install fonts/cyberbit-ttf and run:
% pango-view --font='Bitstream Cyberbit' -t foo
pango-view: Error detected by libpthread: Invalid mutex.
Detected by file "/home/builds/ab/netbsd-4-0-RELEASE/src/lib/libpthread/pthread_mutex.c", line 334, function "pthread_mutex_unlock".
See pthread(3) for information.
>Fix:
Can be worked around with "PTHREAD_DIAGASSERT=AEl" trick.
