Apport gets stuck and sucks CPU

Occasionally apport gets stuck and starts taking all of my CPU. It seems to be related to the attached crash file.

Strace looks like this:
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0xb) = 1

The open files look like this:
