> This was reported in Debian quite some time ago (I was not maintainer then).
> I have fixed it in Debian and am forwarding my patch.
> The original Debian bug report can be found at
> https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=715592
> PSVIWriter uses strrchr but does not properly handle a NULL return value,
> causing strcat to attempt to dereference a NULL pointer.
> My patch adds a check that the result of strrchr (for the '/' case) is not
> null before executing the strcat. The case for '\\' is not affected because
> of the "greater than" check just prior.
