Iceweasel crashes with Bus error

When trying to start iceweasel it just crashes and returns "Bus error"

When running it in gdb i get this:
Starting program: /usr/bin/iceweasel
warning: no loadable sections found in added symbol-file system-supplied DSO at 0x7ffff7ffa000
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Program received signal SIGBUS, Bus error.
0x00007ffff7de85cf in ?? () from /lib64/ld-linux-x86-64.so.2

Could someone please help me with this?
