I have a repeatable segfault that seems to happen while trying to load the application cache from disk.

The ApplicationCache.db itself appears to be a valid sqlite database with no corruption. I can provide a copy if that will help.

Operating system: Linux
                  0.0.0 Linux 3.2.0-4-686-pae #1 SMP Debian 3.2.60-1+deb7u3 i686
CPU: x86
     GenuineIntel family 6 model 69 stepping 1
     2 CPUs

Crash reason:  SIGSEGV
Crash address: 0xb5eb3000
