xsane is segmentation fault and crash frequently

[Midnight Express Ginga81]

When I'm scanning, it stops in the middle of getting data RGB, and then crashes with a segmentation fault (core dump).
In the worst case, even one page cannot be scanned.
But when it works well, it can scan more than 200 pages.
I have no idea why it crash, but I reported it for the first time because I understand that I can report it.
It is very inconvenient because it crashes frequently.
Please fix it.
