Attachment: cairo-crash.txt

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:42.0) Gecko/20100101 Firefox/42.0 SeaMonkey/2.39
Build ID: 20151122033039

Steps to reproduce:

I observed seamonkey crashing quite often. On the console I found the following messages:

ATTENTION: default value of option force_s3tc_enable overridden by environment.
Can't find symbol 'glXCreateContextAttribsARB'.

Actual results:

I attach a gdb stacktrace, do not know why seamonkey itself couldn't provide the detailed stacktrace right away.
