-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello Robert,
I have new information regarding the hangs. I have finally managed to get my gdb to produce a meaningful backtrace when the viewer hangs and this is the result. For DrawThreadPerContext, it is blocked at: Thread 1: #0 0xb7f507f2 in _dl_sysinfo_int80 () at rtld.c:788 #1 0xb7a83206 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/i686/libpthread.so.0 #2
