Sigsegv when opening 7z with subfolder

[GoogleCodeExporter]

Describe your system:
 - Linux distribution: Debian squeeze
 - Machine type: 64-bit
 - Mupen64Plus version: r1404

I used "Pip's Pong by Mr. Pips (PD).z64" to test some stuff and noticed
that I have a sigsegv when compressing it with subfolders. So instead of
compressing only "Pip's Pong by Mr. Pips (PD).z64" I compressed "Pip's Pong
by Mr. Pips (PD)/Pip's Pong by Mr. Pips (PD).z64". It seems that it only
crashes when the romcache reads it.

Backtrace:

Thanks for the bug report and patch.  This code has been removed from the
newly-redesigned emulator software.  This will be helpful if any front-end 
projects
pull the romcache code from earlier Mupen64Plus builds.
