xv will generate a SEGV after 1) loading a 24 bit JPEG
2) applying a gamma correction (of 2) and 3) trying to
print it. The SEGV occurs in free() called from writePS()
Unfortunately, XV hasn't been updated in a long time, and I doubt it
will be anytime soon. We are going to stop shipping xv with the 6.0
release as it also doesn't fit our software requirements for the main
distribution (it is shareware, not open source). I suggest you report
this bug directly to the XV author.
