Description of problem:
I am attempting to get my Canon ImageFormula P-150 scanner to work under 32-bit Fedora 22.

The first problem I got was it wouldn't find the scanner at all. Then I was able to get sane-find-scanner and scanimage -L to find it, but then xsane crashes with memory exceed error.

Version-Release number of selected component (if applicable):
0.999

How reproducible:
always

Steps to Reproduce:
1. plug scanner above into USB ports
2. run sane-find-scanner, scanimage -L to verify scanner is there, connected
3. run xsane

Actual results:
$ sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

$ xsane

Segmentation fault (core dumped)


Expected results:
xsane finds scanner and can scan documents with scanner.


Additional info:
Xsane with this scanner used to work under F17-x86_64 using setarch i686 xsane. This no longer works with the F22 as I am unable to install 32-bit xsane under 64-bit F22. So I am trying with 32-bit F22 under Boxes.
