[sane-devel] XSane preview crashes under FreeBSD

[Alex Teslik]

Hi Oliver,

I am using 0.87. Unfortunately there is no FreeBSD port for 0.89 or 0.88 and I
don't have enough time to do a source build without the port patches. I
emailed the maintainer of the port, but he is very busy right now with exams,
so I might do the port if I have enough time during this pre-Christmas season.
In the meantime, the good news is that I disabled autoselect area in the
preferences and this problem completely went away. I will get to 0.89
hopefully soon and let you know if that solves the problem as well.

Thanks,
Alex
